The Libertarian Bizarro World/appropriation
From Critiques Of Libertarianism
So the thing to look for when reading a libertarian theory of initial appropriation is how they choose to hilariously turn all of this on its head. All of a sudden, once someone unilaterally asserts ownership of something, moving about the world freely somehow gets recategorized as violating other people's liberty. Even worse, moving about the world freely is even recategorized as aggressively attacking someone!
