Christopher Beam's piece on libertarianism had some amusing moments:
Say we started from scratch and created a society in which government covered only the bare essentials of an army, police, and a courts system. I’m a farmer, and I want to sell my crops. In Libertopia, I can sell them in exchange for money. Where does
the money come from? Easy, a private bank. Who prints the money? Well, for that we’d need a central bank–otherwise you’d have a thousand banks with a thousand different types of currency.
Addendum: Scott Sumner has other bones to pick.
