Full disclosure — I am not an anarchist, though if my answer is answered thoroughly I might become one.
At the very least for the anarcho-communists that I know, they agree with dialectical materialism to some extent. As such, they understand that feudalism was defeated and replaced by capitalism with the use of a revolutionary bourgeois state.
If they admit and understand that the victory of capitalism over feudalism was through the use of a state, why would the victory of communism over capitalism be any different?

I think there's many layers of fallacy to chip away at here.
Dialectical materialism is at best just philosophy at worst religious fundamentalism - dialectics can only negate, so they can't actually prove anything. I suggest Jacob Blumenfeld's book on Max Stirner.
Then we get to the myth of progress. Feudalism to Capitalism wasn't a positive thing for most people, not that either state was desirable.
But the real problem is thinking that the problem is the economic system. The problem is in authority. The end goal is not the creation of a benevolent centralised system, but of distribution of authority such that there is no system for which domination can take root. Capitalism collapses if there is no authority enforcing property laws.
I can go more in depth if you want.
