Circle-A in the Holy See


I've been known to joke that Vatican City is the only truly libertarian country, since it's all private. Now Carlo Lottieri has written a paper that seriously contends that the Vatican is not a state but "the outcome of free and spontaneous relationships, in absence of any kind of violence." I'm not persuaded, but it's certainly an interesting argument -- and I suppose it might explain why their postal service is so efficient.

Next question: Are the Knights of Malta a state? What about UN headquarters?
