We must recognize that only scarce resources are ownable; second, that the body is a type of scarce resource; third, that the mode of acquiring title to external objects is different from the basis of ownership of one's own body.

Because the state necessarily commits aggression, the consistent libertarian, in opposing aggression, is also an anarchist.

The libertarian approach is a very symmetrical one: the non-aggression principle does not rule out force, but only the initiation of force. In other words, you are permitted to use force only in response to some else's use of force. If they do not use force you may not use force yourself. There is a symmetry here: force for force, but no force if no force was used.

To be an anarchist only means that you believe that aggression is not justified, and that states necessarily employ aggression. And, therefore, that states, and the aggression they necessarily employ, are unjustified. It's quite simple, really. It's an ethical view, so no surprise it confuses utilitarians.

Artists are just entrepreneurs. It's up to them to figure out how or if they can make a monetary profit from their passion − from their calling, as I discussed above. Sometimes they can. Musicians can sell music, even in the face of piracy. Or they can sell their services − concerts, etc. Painters and other artists can profit in similar ways. A novelist could use kickstarter for a sequel or get paid to consult on a movie version.

The basis of self-ownership is the fact that each person has direct control over the scarce resource of his body and therefore has a better claim to it than any third party (and any third party seeking to dispute my self-ownership must presuppose the principle of self-ownership in the first place since he is acting as a self-owner).

The Austrian theory of subjective value teaches us that there are many ways to incentivize or motivate or induce someone to commit an action for you: you can promise sexual favors, promise to pay money, hire someone, and so on. Also, there is no reason to think that both the boss and his underling cannot both be 100% responsible: in the law this is called joint and several liability.
