Unassailable argument for property rights?:
Does my body belong to anyone? Who? What about the knowledge in its brain, or the computations that it's carrying out? Or its sense of self? Ownership does not apply to these things? Anyone has as much of a claim to them as me? If not, and I do own these things, then ownership is indeed an unrefuted theory with respect to them. Then, why are these things a different case from other objects and processes, such as those in the room around me, and onward (per explanations, as the case may be)?
