It is my understanding that the basic teaching of anarcho-capitalism is to allow so much freedom that society becomes unmanageable so that we beg for communism.
I believe you nailed it.
I think this an incorrect conclusion, as the notion that "so much freedom becomes unmanageable" is itself fallacious. A basic view of the dissonance between the state (and its ability to coerce) and freedom is that of a range of definitions as to what a state is and how pervasive and powerful it can become.
The State -- capitalized -- becomes its own reason for being under various forms of rule. Slavery and feudal systems through to that pretend democracy which is majoritarianism have historically shown a range of evils and corruption.
Many have seen the State as that entity in which abuse too easily takes place, and so some theorize that one can do without a state (in the lower case). But the various forms of Communism are all statist, such that to say the anarcho-capitalist thinks "too much freedom" will collapse is itself a camouflaged statist accusation.
Some in the 20th century posited that there is a ratio. More state means less society, and more society means less state, so to speak. What is certain is that some minimum elements of a state are necessary. So one cannot easily live as a purist anarcho-capitalist. Basically it's a lot of verbiage to theorize a bit.
More power to the state? Less power to the people. And vice versa. The work of Elinor Ostrom in this regard (see her 2009 Nobel speech) suggests that localizing decisions is the best form of "management" in solving the so-called problem of the commons. Certainly, centralized control as in National Socialism, Italian Fascism, and Soviet and Sino-Socialism (Communism) is by default does not deliver either local control nor greater freedom. The smallest possible state, restrained from becoming a State, is the dream and as best I see it was the dream of the Founding Fathers. Therefore its Republic is intended to guard against majoritarianism.
I don't think one can find many anarco-capitalists advocating for Communism. If you could cite some, this could become an interesting discussion. Best wishes.
