Why do you claim that Somalia is a libertarian paradise? Libertarian don't claim Somalia.
Libertarians generally look to the most free countries in the world, such as the U.S., Chile, Switzerland, Singapore and New Zealand, and then identify where these countries are inconsistent with their commitment to freedom.
BTW According to Freedom House, Somalia is one of the most unfree countries in the world, just this side of Cuba.
And, on the issue of drugs, are you saying that Somalia has a liberatarian approach to drugs? I thought repressive Muslim countries have the kind of drug policy that conservatives advocate, but what do I know?
VonMises.org had an email out recently describing how Somalia can function [such as it does] without a true central Government. It is very much a clan or tribal thing. There wasn't that much in the article in terms of making that case that this was a good thing. The email did to some extent explain why the half hearted attempt at humanitarian aid and nation building a la the 1990s was doomed to failure.
BTW as I understand it,the anarchist wing of the small "l" libertarians, really does exist. Rothbard a leading libertarian of the recent past was an advocate of no government. I consider myself to be a libertarian, but Rothbard's belief in the idea of the benefits of anarchy is / was total nonsense.
