Curious about how this goes but not masochistic enough to enable comment notifications...
Hope some enjoy!
Just because I don't think those theories are true doesn't mean I think they couldn't be proven true. Anarchism is also a political theory based on observable phenomena supported by empirical evidence. It is very contradictory to the theories you bring up which means they can't all be true, even though they're all published theories. We could do a big experiment to figure it out though. We'd just need to first get to a communist society, then we can see if it can sustain itself or if hierarchies naturally dominate without outside influence. I'm willing to be proven wrong, are you?
