Anarchy, State, and Market Failure If my grandpa steals all your land then leaves it to me in his will, would you and the courts be the aggressors when you try to get your land back? I didn't do anything wrong? — ZhouBoTong
There's a salient difference between theft and murder. In the case of the former, some form of compensation, or even restitution, is possible. In the case of the latter, it's plainly not. If my grandfather was a thief, I may justifiably lose property I possess that originated in his acts of thievery, provided solid evidence of such acts. If my grandfather was a murderer, I may not justifiably lose my own life.
Regarding "aggressive marketing campaigns", I have to confess that I am having a hard time grasping just what in the world the argument is supposed to be. Yes, things can be colloquially described as "aggressive". No, that doesn't mean that they are aggressive in the philosophically relevant sense. One might as well accuse libertarians of illicitly "changing the language!" because the libertarian principle doesn't prohibit "passive-aggressive behavior" and doesn't compel us to be particularly kind to our fellows.
