> This is the thing I don't understand about (a superficial interpretation of) anarchists

I think most superficial interpretations of anarchists are based on edgy LARPers rather than real political ideology.

Fun fact: Anarchy means "without rulers", not "without laws" or "without social order". There's a wide diversity of political thought under this umbrella, but the key underlying common denominator is (on some level, at least) a rejection of hierarchy (and often a rejection of capital).

Though it's fun to imagine what the philosophical and political beliefs that underpin a colloquial understanding of the word might look like, the answer is usually simply: Teenagers.

Maybe don't be so dismissive of that which you lack a thorough understanding.

Recommend reading "Against the State" by James Stout, wherein he describes history of various Anarchist societies, including Barcelona during Spanish fascism, Myanmar where they are very successfully fighting the junta which wrested control from their civilian government, and Rojava where he personally visited and gives a firsthand account.
