I don’t think there’s anything wrong with it. It’s closely aligned with my philosophy: Morality from a Societal Perspective. I’m basically viewing natural law as objectively discoverable, but at the same time as social contract, and one must choose to live either peacefully (cooperate) or to be animalistic (aggressive).
I believe Hoppe has the same view ( The Reason to Peacefully Cooperate ), and he quotes Mises powerfully too.
