Rothbardian ethics are just an excuse to suppress the strong’s ability to use violence while maintaining the cunning’s ability to entrap, lie, cheat and steal.
Liberty was created at the point of a sharp metal object, by heroic males, as a means of suppressing all forms of cheating on the backs of others.
Rothbard’s pretense is simply a means of justifying parasitism on that hard won liberty.
There is nothing libertarian about Rothbardian ethics.
Its just a complex philosophical lie to justify immoral and unethical theft.
