Rothbardian ethics only require ‘satisfaction’ or ‘psychic benefit’ or ‘voluntary cooperation in absence of the threat of violence. This is acceptable ethical criteria for exchange between states.
However in-group ethical and moral codes evolved to prohibit free riding and parasitism. Such that the standard of ethical exchange is not ‘psychic’ alone, and therefore tolerates, licenses, and encourages deception; but objective, in that in-group trust requires that exchanges are objectively productive in addition to subjectively voluntary.
I used to think Rothbard had simply made a mistake. However, it’s pretty hard to think that he was doing something other than trying to justify parasitic ethics as moral.
Rothbardian ethics are immoral, unethical, parasitic and the reason the liberty movement has failed. Aristocratic Egalitarian (protestant, high trust) ethics are the only ethical scope of constraints that will allow for the formation of a voluntary polity capable of anarchic or private government.
The total prohibition on free riding. The requirement for fully informed, warrantied, voluntary exchange, free of negative externality.
**Why would one argue for an unethical and immoral scope of ethical constraints unless one was himself an immoral and unethical man?**
