There are two libertarian traditions; The christian aristocratic classical liberal (epitomized by Hayek) and the jewish merchant anarchic (epitomized by Rothbard) Christians were a land holding majority and so needed formal institutions. Jews were a diasporic religiously governed minority and favor anarchism. With the heavy jewish immigration into the USA, jewish authors advocated their means of avoiding the oppression of the state just like christian classical liberals advocated their means of avoiding oppression by the state. These two traditions became allies. Then Rothbard and Friedman became the primary intellectual advocates for libertarian policies. There has not been an evolution in christian classical liberalism. This is partly because institutional programs are nearly impossible to put into place, and ideological programs that require only ‘belief’ or ‘support’ are much easier to put into place. It is also a failure in part, because classical liberalism is an institutional model that can resolve conflicts in priority among people with similar interests, but it cannot provide (majority rule cannot) a means of resolving conflicts among people with dissimilar interests. (As they warned us in Federalist Papers 10.) The recent dominance of Rothbardianism on the internet, can be largely attributed to Lew Rockwell’s insight that it was possible to adopt the ideological tactics of the communist movement, and the organizing tactics of Alinsky to promote libertarianism as an ideology through education and community building. His impact through the mises institute cannot be overstated. So, in essence, we have not created the next evolutionary step in classical liberalism in order to solve the problem of running an empire in a modern economy where the institution of marriage has become unbound and where women and men have different reproductive strategies and therefore different political sentiments. THe libertarians (Hans Hoppe in particular) have devised some solutions for small states. But no one has yet determined a solution for large scale states that desire to federate. As such, because of this failure, the debate for freedom takes place largely in the context of anarchism. Because the jewish anarchists have supplied the only ideological program that can compete with social parliamentary democracy (ie: it’s communism by other means.)
You could look at the problem this way: jews have always been a minority and christian classical liberals are becoming a minority — and beginning to act like one. Only majorities look to provide institutional solutions. Small groups stick with informal institutions: religions and norms. Because they lack the power to create formal institutions.
That’s a lot to cover in one note. But it’s the answer you’re looking for.
