There are two basic veins of libertarianism in the world. There is the state-centric vein found most clearly present in the Libertarian Party, as it seeks to take control of the government and reign in power to a smaller scope. Then, there is the philosophical anarchist vein, which seeks to abandon temporal government altogether.
Both veins are libertarian, and Michael Badnarik, the 2004 U. S. Presidential Nominee for the Libertarian Party and I discussed some weeks ago how that these two schools of thought meet or come most closely together at minarchism.
It has been an interesting exercise for me to inject the philosophical anarchist vein into the Texas Libertarian Party over the past months, as they first turned their nose up at my proposal to "run for Texas Governor and then refuse the oath of office" (an application of Tolstoy). Now, I am getting some positive responce within the party, as they realize that my views are pure Rothbard ("Mr. Libertarian"), tightly connected to Rockwell's approach.
My goal was to unite both veins of libertarianism into a more powerful Libertarian Party, and I can see eyes opening to that end.
