For Avengers 4 to truly be the endgame of the first decade of the Marvel Cinematic Universe, it needs to conclude with the Infinity Stones going away. The six ancient power sources embodying the concepts of Space, Time, the Soul, the Mind, Power, and Reality have been omnipresent since the early years of the MCU, serving as plot devices, MacGuffans, and deus ex machinas depending on what each particular movie required. But by the time Avengers 4 ends and Phase 4 kicks off, the Infinity Stones need to be purged from the MCU going forward.

In Avengers: Infinity War, Thanos assembled the six stones into the Infinity Gauntlet so he could achieve his master plan of wiping out half of all life in the universe. The fallout from the Mad Titan's ultimate victory will have to be dealt with by the surviving Avengers - who will also have to somehow resurrect the lives Thanos took, including the dead heroes like Doctor Strange and Spider-Man - but exactly how they can win the day is a closely-guarded secret. However, it's hard to see how the Avengers would allow the Infinity Stones to continue to exist, leaving them for Thanos or the next insane cosmic being to come along may attempt to collect them again. That would be tempting fate for yet another universal catastrophe.

Most of the superheroes didn't even know the Infinity Stones existed prior to being pulled into the war to stop Thanos, so it made sense they made no effort to secure or destroy them. But now, the Avengers know exactly how dangerous they are, both individually and especially together. It's unclear whether the stones can be destroyed, but nevertheless, it wouldn't make sense for the heroes to let the stones remain accessible in their universe. Furthermore, here's why it also doesn't make sense for the MCU to retain the Infinity Stones as a narrative device moving forward into the future:

The Infinity Stones Are Products Of MCU Phases 1-3

The Infinity Stones were a fantastic idea to tie together the MCU and create a goal for the ultimate villain, Thanos, to work towards. By weaving the existence of the Stones throughout the various Marvel movies, they helped bond the universe, their many characters both in space and on Earth, and deepened the MCU's history. Loki wielding the Mind and Space Stones as he led the Chitauri invasion of Earth was also a brilliant reason to bring together the original six Avengers and conclude Phase 1. MCU Phases 2 and 3  were about uncovering the other four Infinity Stones in Thor: The Dark World, Guardians of the Galaxy, Doctor Strange, and finally Avengers: Infinity War.

But now that Thanos has all six Infinity Stones and achieved godhood, there's nowhere else narratively to go with the almighty power sources (besides telling the story of how the Titan loses his newfound omnipotence). There's no benefit in rehashing the chase for the Infinity Stones in future films, especially when Phase 4 and beyond are an open book to tell new kinds of stories with new superheroes.

Most Of The Phase 3 Films Worked Without The Infinity Stones

Captain America: Civil War traded on fans' loyalties to and affection for the Avengers as they split them apart - not over the Infinity Stones but over political and ideological differences. After the Time Stone was introduced in Doctor Strange, the next four MCU films - Guardians of the Galaxy Vol. 2, Spider-Man: Homecoming, Thor: Ragnarok, and Black Panther - were each wildly successful and most of them didn't even utilize the Infinity Stones. The Space Stone in Thor: Ragnarok was merely a throwaway to help set up Infinity War. It's actually quite telling that despite Loki taking it from Odin's Vault, the Revengers never even tried to use the Space Stone's power against Hela. (Hela herself dismissed the Space Stone entirely when she saw it, preferring to rely on her own formidable powers).

Despite rampant fan speculation that the missing Soul Stone was in Wakanda, Black Panther disproved that theory. What's more, thanks to its superbly realized world-building of the Vibranium-rich, hidden African nation and its cast of fascinating, instantly iconic characters, the film never needed the narrative crutch of an Infinity Stone to become a record-breaking and crowd-pleasing blockbuster. Marvel has explored different genres and expanded what a superhero film can be without repeating their original 'formula' of a superhero origin tied to an Infinity Stone.

It makes sense that the Infinity Stones were de-emphasized by Marvel to avoid overexposure and give the almighty objects more credence in Infinity War, but what the MCU also established in the process is that they have the ability to tell fantastic stories and create compelling new worlds within the MCU without relying on the Stones. This is a plan they would best continue in the future.

The Infinity Stones Have Outlived Their Usefulness

To Marvel's credit, they were able to take the concept of six colored rocks with vague magic powers and make them a consequential threat sought by a giant purple space alien - and it all worked wonders. Thanks to how Marvel never truly clarified each Infinity Stone's powers (most are capable of firing a colored energy beam), they also have been useful plot devices in other ways, such as how the Mind Stone gave Scarlet Witch, Vision, and Ultron their superpowers (and in the case of the androids, sentience). The way each Infinity Stone was seeded throughout the MCU and tied to particular superheroes like Doctor Strange, the Guardians, and Thor over the course of multiple films was masterfully done. But it has indeed been done.

All things considered, the Infinity Stones probably could not have been better utilized in the MCU, but their usefulness is at an end. Now, they can't be seen as anything more than a massive threat to the entire universe. It wouldn't be believable that anyone trying to possess them after Thanos would not use them nefariously or would only try to keep them "safe" - nor should the Avengers take that chance. In fact, it will be particularly interesting how Marvel handles the Time Stone going forward. Also known as the Eye of Agamotto, the mission of the Sorcerer Supreme is to safeguard the Time Stone. When he's resurrected, Doctor Strange may have to choose to sacrifice that mission and the Time Stone for the good of the universe.

The MCU Has Introduced Other Concepts To Replace The Infinity Stones

As Phase 3 continued, the MCU has gradually found other means to replicate the powers of Thanos' magical colored rocks. Doctor Strange's battle with the Great Titan showcased his mastery of the mystic arts; the wizard was able to go (briefly) toe-to-toe with Thanos while he possessed five Infinity Stones. In their battle, Strange displayed a control over reality that rivaled what the Reality Stone can do. Thor's Stormbreaker axe can open the Bifrost and allows him to teleport anywhere within the Nine Realms, which is essentially the same power as the Space Stone. Scarlet Witch proved she was powerful enough to hold off Thanos and destroy the Mind Stone simultaneously.

As for time travel, Ant-Man (and later Doctor Strange) introduced the Quantum Realm, an otherworldly dimension where time and space have no meaning, which is accessible by shrinking microscopically or by magic. Ant-Man and the Wasp further explores the mysterious Quantum Realm, which may play a huge role in how the Avengers will defeat Thanos in Avengers 4. As a result, the Time Stone no longer seems as singular or special now. With the rumored introduction of the Eternals in Phase 4 as well as the long-awaited arrival of the cosmic-powered Captain Marvel, the MCU has leveled its playing field in terms of sheer power. As storytelling devices, the MCU now has various and more interesting means to move past the Infinity Stones.

Marvel definitely deserves praise for how well they utilized the Infinity Stones in the MCU, but once the dust of Avengers 4 settles, the universe will no longer need them, and would be better off without them.
