The laws of our land and our government change daily. You can philosophize about unchanging principles or morality if you wish, but the law is defined by statue, written and and agreed upon by men. If they weren't we would even be on this website because everything we discuss would be moot.
Even Story, an unabashed federalist, said that decisions of the court were not law, but were merely "evidence of the law".
There are about 1200 years of legal philosophy, from Bracton to Coke to Montesquieu to Kempis to Locke that disagree with you.
We cannot make law. We can only discover it.
