You think there is no authority in anarchist government? Have you ever read about horizontal-democracies?
Anarchist just means “against coercive authorities” namely “centralized and hierarchical governance”
You realize the fediverse that creates lemmy is an anarchist structure right?
Generally anarchism does reject the idea of authority wholesale whilst also having no historical basis for it. Those societies were clearly in a very different place. I suggest you look into dialects as they will provide comprehensive explanations as to authority and its foundations (and why there are different conditions then than now) especially seeing as they fully had “coercive” authority. Now as to what non-coercive authority is, I don’t think even the anarchists have cracked that one
