Yep. This is a good quote from Rothbard about the mistake I believe Borer makes and Block refers too?

“The error here on the part of the “contextualist” libertarians is to confuse the question of the moral course of action for the person in such a tragic situation with the totally separate question of whether or not his seizing of lifeboat or plank space by force constitutes an invasion of someone else’s property right. For we are not, in constructing a theory of liberty and property, i.e., a “political” ethic, concerned with all personal moral principles. We are not herewith concerned whether it is moral or immoral for someone to lie, to be a good person, to develop his faculties, or be kind or mean to his neighbors. We are concerned, in this sort of discussion, solely with such “political ethical” questions as the proper role of violence, the sphere of rights, or the definitions of criminality and aggression. Whether or not it is moral or immoral for “Smith” – the fellow excluded by the owner from the plank or the lifeboat – to force someone else out of the lifeboat, or whether he should die heroically instead, is not our concern, and not the proper concern of a theory of political ethics.[5] – Lifeboat Scenario, TEOL – Rothbard
