Good enough for Rothbard, good enough for me.
The movement that I’m in favor of is a movement of libertarians who do not substitute whim for reason. Now some of them do, obviously, and I’m against that. I’m in favor of reason over whim. As far as I’m concerned, and I think the rest of the movement, too, we are anarcho-capitalists. In other words, we believe that capitalism is the fullest expression of anarchism, and anarchism is the fullest expression of capitalism. Not only are they compatible, but you can’t really have one without the other. True anarchism will be capitalism, and true capitalism will be anarchism.
You have said that you prefer to be called anarcho-libertarian. In light of this quote, isn’t anarcho-capitalist more approriate for a Rothbardian?
I personally like anarcho-capitalist. For me it is such an kick-ass title. But I guess it depends on personal taste and cultural context.
I think he was using “capitalist” as a rough synonym for libertarian, back then, because of the influence at the time of Randians who often did this. I sometimes use the term myself, even though I think technically it has some defects as a synonym.
