Don’t get me wrong. I am all in favor of leaving adults free to experiment with all sorts of things. But the FDA’s action has driven the experimentations underground. These should instead be in the light in order to give companies the strongest possible incentives to not kill their consumers.
Tariffs make us worse off, but they are relatively easy to implement and hard to repeal because of the incentives inherent in the political system. Understanding a problem is the first step toward fixing it, however, and with the 100th birthday of the economist James M. Buchanan  coming up, maybe we should be hopeful, if not necessarily optimistic, that public understanding of economics will someday advance to the point that tariffs are just a little bit lower than they are now.
