might nonetheless seem strange to devote so much space towards regulatory possibilities and difficulties in a bioethics article. In fact, I think that to move from theory to policy it is essential both here and elsewhere in bioethics to focus on these regulatory issues and that we should viewthe“can”and“ought”questionsasatleastpartially intertwined: Familiarity with the available regulatory levers and their drawbacks is useful in calibrating our normative views about what we should do in all things considered terms. For example, for those with libertarian or statist priors on medical tourism, difficulties in implementing interventions in this sphere count as further reasonstoopposedoingso;forthosewithstronglypaternalist or cosmopolitan priors, showing that some tools areavailabletoregulateallowstheclearingofathreshold objection to acting; and for those in between, the desirability and administrability of these interventions help us to reach reflective equilibria on our views on the ultimate question of whether to intervene.
