Yeah, I tried to cut the line at “trading money” as opposed to a general examination of libertarian principles. But I agree that for euthanasia, once you start considering higher-order effects, it’s not clear that it’s net positive for society. For example, if I definitely never want to do euthanasia, then legalizing it does seem to hurt me. Because maybe someday and I’m old and disabled and my children have to go to enormous effort to take care of me. Even if they’d never consider the idea the idea of euthanasia, the mere possibility of it might make me feel like more of a burden to them and make me feel guilty for not doing it.

Of course there are obviously downsides to making it illegal, too! I don’t really have a strong view on which is net-positive. Seems very hard.
