[T]he ruling caste are the people who say "we" when they mean "the government". The ruled castes always say "they". - Curtis Yarvin

This is how Rothbard so frequently reasons himself from Lockean absolutes to sheer insanity. He is a master of the reductio ad absurdum, but so stubborn that he defends the absurdum.

(The United States’) industries are gutted and vanished. Her finances are ruined beyond imagining. Her old cities, but for a few, are dirty, dangerous, unlivable. Millions of feral, armed savages, perfectly de-civilized, run wild in her streets. Her famous social fabric is shredded, her famous voluntary institutions defunct, her population bored, lonely, atomized. Her small towns have rotted, turned into strip-malls, or both. (Her birds, however, are remarkably well-protected.)

There is no reason at all that a libertarian, such as myself, cannot favor martial law. I am free when my rights are defined and secured against all comers, regardless of official pretensions. Freedom implies law; law implies order; order implies peace; peace implies victory. As a libertarian, the greatest danger threat to my property is not Uncle Sam, but thieves and brigands. If Uncle Sam wakes up from his present sclerotic slumber and shows the brigands a strong hand, my liberty has been increased.
