Ever notice how nearly all articles about economic theory immediately gather the "ivory tower intellectual who has no concept of the real world - everything they study is in their own thought bubble" criticism?<p>That same criticism applies to libertarianism - they're interesting ideas, but not implementable as stated. The number of countries that have implemented even half of what they propose is a null set.<p>Not to say it wouldn't work, but you'd think at least someone would try it out somewhere and we'd have one datapoint...
