This really is not the message though. From the post:

“That’s why the worst possible reaction to a failed intervention is resignation. We may not know enough to improve our lot right now, but perhaps we could figure it out, if we tried.”

From reading the whole post, I gather that he’s truly not advocating some libertarian angle, he really is writing on the observation that policy is hard, and it’s nearly impossible to actually predict all the effects of societal intervention.

From my reading, I’m not sure even sure that he’s advocating caution or reluctance to social policy. Just goat sacrifices!
