The present paper discusses Wollen’s dilemma and recent libertarian responses thereto. Wollen (2022) argues that libertarians face the following dilemma. If one of the conjoined twins wants to commit suicide by a lethal injection to their single heart, libertarians cannot allow it, for doing so would violate the other twin’s self-ownership right not to have the heart stopped. But they cannot forbid it either, for doing so would violate the former twin’s self-ownership right to stop the heart. In response, Block (2022) argues that libertarians can solve this dilemma by flipping a coin. In turn Nowakowski, Slenzok and Wójtowicz argue that there are two alternative solutions available to libertarians and so no coin flipping is needed – a joint ownership solution which forbids the suicide and an individual ownership solution which allows it. The present paper argues that none of these solutions is optimal. It submits that the best solution is actually much more straightforward and simple. The twin may not commit suicide because under libertarianism, the same as under virtually any existing legal system, no one may use his own property so as to injure another: sic. utere tuo ut alienum non laedas.
