Anarchism, to me, is the thing people did before someone decided to do otherwise. It doesn’t matter that it’s how most human beings “naturally” congregate, because the fact is that the very moment someone decides to start consolidating power, they seem to do so successfully. Every state began with someone with a clear goal gathering other people with the same goal- and often, then gathering people who don’t share that goal through force. Clearly Anarchic societies failed to prevent that process from occurring, they are not hardened against violent, coordinated groups. Saying that “the majority of societies were essentially anarchist” fails to notice that far, far, FAR more people have existed within “stateful” societies. More individual anarchist “structures” vs. many more people consolidated within stateful structures is just down to the nature of both.
