anarchy as a model of government in a scale of 8 billion people makes no sense and would be basically the most violent ends up getting everything. As a mental experiment in the rainbow and lollipop world is alright and I would definitely be onboard, but in practice it makes no sense because you need too much power to enforce it, and that is where the corruption would originate.
But my main point was not to only criticise communism, but also capitalism. I don't think communism is achievable and I don't think pure unregulated capitalism is the only crap we can aim for. Hence middle point or just nuance.
Online people, specially online USA people, are very prone to "choose a team and die for it" or "we have to go full communism or it doesn't make sense" or "communism is bad so let's do 100% uncontrolled capitalism". There is no middle point for these wankers (which is very convenient for the politicians and wealthy people, as they get to abuse the argument of reducing everything to the absurd)
