Dalrymple takes a surprising policy position in a piece for the Library of Law and Liberty, but of course he is also making a point about personal responsibility:

I would have no real objection, then, to regulation of the sugar content of prepared foods, provided it was done on intellectually honest grounds. Those grounds would not be that people are incapable of acting other than as they do, but that they are too idle to cook, their tastes and pleasures are too brutish, their habits too gross, for them to be left free to choose for themselves. Someone who knows better must guide them.
