From what did that “violence” (Beliathon) originate (if not from “[h]uman nature” [Beliathon])—?

The NAP simply recognizes that no one has the moral right to initiate force upon any individual and there are no exceptions for groups of individuals or any organization calling itself the govt.
Self defense is not at all incompatible with the NAP.
