Nope! I'm referring to Dejacque's publication of
Le Libertaire, an anarchist journal which was of course avowedly socialist. But as long as you're referring to Wikipedia,
the "libertarianism" article does not seem to be your friend:
I do agree with the comment about economic freedom, which accounts for the incompatibility of libertarianism with capitalism.
There's a Zapatista libertarian for you. Does that help?
Actually, the vast majority of all existing anarchists believe that. While anarchism as I define it is a political philosophy that has existed for 160 years and has been promoted by millions, "anarcho"-capitalism is a marginal Internet philosophy that has never achieved the slightest semblance of implementation...or even influence, for that matter.
