Unrelated point: It’s interesting that Estlund appeals to the quasi-libertarian idea that even though the majority may not know what it’s doing, we shouldn’t boss it around.
The problem is that very often what the majority wants to do is boss people around. If a panel of economists prevents the majority from imposing a tariff, for example, they aren’t so much bossing the majority around as preventing the majority from bossing consumers around.
In any case, if you think that it’s arrogant for people to boss others around just because they know better, how much more arrogant is it for people to boss others around even though they don’t know better?
