What you are talking about is the utilitarian answer to the question. I (and most people currently living in the western world) prefer the Natural law argument IE laws are based on the " Naturally occurring" IE law should be based on principles like equality, freedom, and impartiality that exist even in the absence of government. Nale's view is far too narrow , I think this is actually his Herald's madness, and since the skybreakers see him as the ultimate authority over laws and legality they follow him lead in this and so believe in a view of law that overemphasizes trust and compliance. Many of them may doubt it is possible to swear the third ideal.
