"I don't think it's appreciated enough that some forms of regulation actually do make things better for everyone, and that acting only in one's own self-interest can lead to results that are provably worse for your own self-interest."

As someone who is libertarian-ish, I find that a funny thing to say which doesn't jive with reality. Western countries usually have huge governments with huge amounts of regulation, and the default assumption of almost everyone around me seems to be that regulation is the way to deal with almost anything we don't like.

So saying that it's not appreciated that some regulation makes things better for everyone sounds to me like saying "it's not appreciated enough that clothes make us warm".

(Unless, of course, you're referring only to specific circles, e.g. libertarian economists).
