The vast majority of such justifications are hollowEh, depends on the law in question. Banking regulations, for example, protect consumers and the broader economy from short sighted actions in the part of bankers. I don't think the justifications are hollow given the history.

Well, if you believe citizens are too short sighted to vote rationally, then I don't know how you can argue that they are not too short sighted to make other decisions rationally.
But more to the point, some laws are truly intended to protect people from their own decisions (often in the context of hardships, such as usury laws), but many are intended to protect society as a whole, where the belief is that individuals are harmed collectively by the actions of others.

I don't feel like drug laws and market regulations have much in common.
