WindWip Marx's book A contribution to the Critique of Political Economy clearly states that to move from one stage to the next requires an overthrowing of the political institutions. I could find 50 more sources in 5 minutes if u want.

Good, but why bother. Marx is only of historical relevance . We have over a hundred years to ponder what he said. But times change, people change, the technology has changed. And above all communism has changed. His view of violent revolution reflect the knowledge of capitalism that he had at the time. That form of capitalism has also changed.

I said I haven't seen a strong argument for that - are you now going to prove to me that I already had?

Depends, as i asked, what does better imply? Better in that it is subjectively personally better, or better as in evolution attempts to improve on previous efforts.

You could have easily said "people used to think the world was flat, and that was completely rational at the time", but it's NOT rational - then or now. It had no evidence to support it, just like there was no valid reasoning for why women shouldn't vote.

I could have but then that would have been a straw man.
Instead i used the example of woman suffrage because like any philosophical view, which both woman suffrage and anarchism are. They are dependent on acceptance of the idea.
Unlike your straw man example of the flat earth which is a empirical fact that no amount of philosophising will change

Instead of giving me the same straw man argument again, give me a reason why you think that a anarchist society with no central government can thrive, or even exist.

Because any form of centralised government inevitably leads to revolution whether violent or not. Change is the only consistent factor in society and a centralised government apposes change.
