Surprise! Walter Block is still a raving lunatic.
From Libertarianism vs Objectivism; A Response to Peter Schwartz, Reason Papers, Summer 2003.
Suppose that there is a starvation situation, and the parent of the four year old child (who is not an adult) does not have enough money to keep him alive. A wealthy NAMBLA man offers this parent enough money to keep him and his family alive – if he will consent to his having sex with the child. We assume, further, that this is the only way to preserve the life of this four year old boy. Would it be criminal child abuse for the parent to accept this offer?
Not on libertarian grounds. For surely it is better for the child to be a live victim of sexual abuse rather than unsullied and dead. Rather, it is the parent who consents to the death of his child, when he could have kept him alive by such extreme measures, who is the real abuser.
