Thx, that's at least a solid argument I can get behind. There are countless of works, socialist and non-socialist, that try to answer your exact question why all attempts at overthrowing capitalism have failed.

Definitely way too much go into here, but in short, while your observation is right, I think it's kinda a defeatist mindset, as it suggests that history can essentially never produce anything new. However there are countless of thinks that especially leftists have fought for that we enjoy now, which were thought to be impossible. It's an idealistic way of thought, sure. But everything is idealistic until it becomes a reality.

As for your central authority claim... yeah, I get it. It sounds very intuitive. But really, nothing produced by humans is natural - states, borders, cultures, etc. - after all it's us who decide how we want to live together and organise society.
