  … it is a necessary condition of an offer's being coercive that the offerer is also responsible for the bad circumstances of the offeree. For example, if we poison you and then offer to provide the only available antidote in exchange for your stamp collection, that is coercive. If you are poisoned in a way for which we are not responsible, and we make the same offer, that is not coercive … as long as those making an offer are not responsible for the circumstances of the potential subjects, their offer is not coercive.
