Anarchocapitalism & Libertarianism vs. Liberty

"?We do need to dispense with ?rulers? and 'subjects?. That is, we need to dispense with the conventional arrangement of a unilateral government ? with an ?external? agency, public or private. That is, with the unilateral (one-way) contract between ourselves and a group empowered with the use of force. But, isn't that anarchocapitalism? No, because anarchy leaves it, vaguely, at that point, without putting anything in its place. And anarchy argues that if we put anything in its place, then its [sic] just a standard government, limited or otherwise.? The late Richard Rieben generously gave us much to feast on in this classic essay that was the introduction to his online Liberty Series booklet."
