Except the AnCaps, but I predict they'll split with the Randians any day now and drop off the map.

Most anarchists don't recognise anarchocapitalism as a legitimate form of anarchism because anarchism is against coercive hierarchy and capitalism is inherently coercive. Plus a real life ancapistan would inevitably devolve into feudalism.

Also a lot of them are Hoppeans and that just makes them authoritarians.
