The article summary at American.com reads:
Now, I'm a pretty libertarian guy, but even I can mumble "public good" and realize there are some pretty good empirical and theoretical arguments for state action in some cases.
But on reading the article, it turns out that Rees's five "best ever" obscure actions can be classified as: deregulation, tax deferral/cut, free trade agreement, deregulation, and deregulation. The best "actions" turn out to mostly involve the government ceasing its actions, or deciding not to do anything in the first place.
Here I was, looking for a challenge to my dogmatic libertarianism, and came away with reinforcement. Sigh. Well, I can learn to live with disappointment.
