There are (STILL) no coercive offers

A has not coerced B by offering surgery and, more importantly, we would never say that B cannot give valid consent to such surgery simply because she has 'no choice'. Because A is not proposing to violate B's rights if B rejects A's offer, even though she will die if she refuses the offer. [...]we don't think the lens of coercion is helpful in evaluating the ethics of offering castration to sexual offenders as a condition of release or with respect to other issues in bioethics such as offering payment to research subjects or to procure organs for transplantation.
