Hans Hermann-Hoppe
Hans-Hermann Hoppe is the Austrian School's endgame: take Mises's magic economics, add argumentation ethics, arrive at gated lordships with the legal right to expel anyone — feudalism, but this time it's freedom.
He's mostly present in Infrared discourse as "Prax" — the meme-shorthand for his praxeology cult and its debate-club descendants. Haz to an evasive opponent (RED PILL NEWS | PALESTINE WAR stream): "You're stuck in the cage with me, Prax, Ben."
The substantive line against the whole school stands regardless of which Austrian is talking: the labor theory of value wasn't refuted, it was avoided — by people whose salaries depended on avoiding it (Ludwig von Mises, Murray N. Rothbard, Economic Calculation Problem).
