Go to wiki, look up libertarianism, look under the section etymology.

In a political context it has always carried the meaning of anarchist - it was coined to differentiate libertarian/anarcho-communists from socialist communists.

When Rothbard appropriated the term for his neoliberal populism in recent American history, even he was drawing from that basis - although obviously in bad faith, since he promotes a platform of oppression.
