This is a visual summary of Stephan Kinsella’s essay “Who is a Libertarian?” by Marco de Wit.
de Wit adds a quotation from Hoppe, “Here the praxeological proof of libertarianism has the advantage of offering a completely value-free justification of private property. It remains entirely in the realm of is-statements, and nowhere tries to derive an ought from an is. The structure of the argument is this: (a) justification is propositional justification—a priori true is-statement; (b) argumentation presupposes property in one’s body and the homesteading principle—a priori true is- statement; and (c) then, no deviation from this ethic can be argumentatively justified—a priori true is-statement.” [Hans-Hermann Hoppe. Economics and Ethics of Private Property, p. 208]
