I think you've said a lot that is in line with the video, tbh. Most of your points accurately spell out why a superhero movie involving a protagonist who disrupts the status quo wouldn't work, mostly because we are living in the status quo and the general audience's main frame of reference -- that which they use to understand the story -- is that status quo is overall good, that there are inevitable bad parts that must come with the good, and that mass change is inherently bad. You even note this last point yourself.

But it doesn't change the fact that the superheros are still, for the most part, not proactively trying to ~~recognize~~ reorganize society, but keep it the same and react to its threats, which sometimes have interesting intentions of reorganization, but ultimately all end up doing an irredeemable act in the eyes of the audience so to signal that they are in fact the bad guy.

I don't think this video is really meant to be taken as "superheros should change the status quo," but more closely look at Graebers generalization and kinda jostle people out of their "the status quo is ultimately good, despite it's necessary evils," worldview. Graeber often said he's not trying to provide an answer or solution to societal organization outside of hierarchical Nation-states, but just to allow people to break out of the traditional mental framework and ask the question, what else could work?
