But Republic City IS his way of doing things. The avatar is all about disbanding of illusions of seperation, and that's what Republic City does, making itself to be the melting pot of all 3 nations.
If you're trying to make the case that the world can continue existing without the avatar, that's obviously true. It was true even before, because they needed to take a 20 year break every time an avatar died. But everything progressive about what makes Republic City what it is is due directly to the Avatar making an executive decision on what Republic City stands for: The merging of the nations.
It's not that simple. If it were, Roku wouldn't have insisted that Aang make good on his promise to kill Zuko over the latter's support for the Earth Kingdom/Fire Nation hybrid colony that would eventually become Republic City, nor would Aang have felt the need to sever his connection to Roku over the same issue. While each Avatar ultimately makes his or her own choices, it's clear that there are certain expectations regarding the preservation of the four nations as separate entities that the Avatars up to this point had adhered to; expectations that the creation of Republic City transgressed upon. This is why I hold that the existence Republic City itself a testament to the diminishing relevance of The Avatar as a messianic guide in the world. In supporting the creation of Republic City, Aang prioritized his own values and judgments over the those that were traditionally taught to the Avatar, much like he did when he chose to spare Ozai's life. Avatar values opposed what would eventually become a symbol of progressivism and unity in the ATLA universe.
