It's ok. You don't have to scale. Just have lots and lots of smaller communes and federate. If email and ActivityPub can work like that, why not AFK communities?

Now that's really not a scientific concept. Just because something does not appear to exist doesn't mean it's not possible. I personally strongly disagree that any form of organization is tyranny: depending on the modes of organizing, it can be pretty liberatory in giving a common framework for empowering me to act in ways i could never if i were alone and isolated.
Building collective power is not necessarily to the detriment of individual power, though i'm not suggesting that finding a balance is always easy.
