Genuine question, what happens in an anarchist utopia when your neighbors decide that they like your land? If you fight back en masse, doesn’t that involve creating a military with a hierarchy that’s ripe for seizing power? How can you maintain the social organization for building fighter jets or aircraft carriers or spycraft without those being taken over and used against the people? If you just don’t, what happens when your neighbors are a global superpower that has all that?
It seems even more impractical and idealistic than Communism, which at least has an answer to that.



You appear to be using the term “capitalism” in a confusing way. From etymonline:
Words can change meaning and all that, but when people complain about capitalism, they don’t mean what you’re talking about. You seem to mean something like “well-regulated free market”, and other people mean “broken, exploitative system that worships greed”
