Fascism has done far more harm to the world. Barely any half-serious anarcho-capitalist has had a hand into influencing much practical policy. Even Milei is backing down from some of his campaign proposals, and he's just gotten elected.

Anachrocapitalist groomers as the image implies?

Hmmm. What about anarchocapitalists that leave capitalist out of their descriptors and larp like they're contemporary versions of the DK-listening, doc martens wearing, spiky hair having kids from the 1980s. And ancaps might be slightly better than the rich people at the top that use every advantage they've been given as a lever to suppress the success of everyone else. At least ancaps still have the potential to change.
