Marx himself said that true communism would need to be stateless, because government is a form of power and therefore a hierarchy.
But without a hierarchy, there'll be nobody to enforce communism, and there'll always be someone trying to step out of line and acquire more material wealth than everyone else because it's human nature to be competitive and want a bigger slice of the pie. And because some people are simply superior to others (not even in a racial way, just in the sense that some people are smarter, stronger, more talented, etc.) someone's going to succeed.
It's nice to imagine a world where there's no hierarchies, but as long as humans are humans, it's not gonna happen. Which is why anarcho-communists are all fucking autistic. Because they don't understand humans.
I just realized this is a Pokemon board and I need to make this related to Pokemon, so I guess I'll point out that the Pokemon universe is one where ancom can function because there's almost no evil people and the handful of evil people who do exist are cartoonishly evil ideologues with ridiculous plans that can never go under everyone's radar.
