It makes perfect sense if you have a basic understanding of Natural Law.
You're basing your entire arguement on a concept of "Natural Law" that can mean whatever you want it to mean. That's what makes no sense.
I wish that the term “natural law” appeared in the actual text of the Constitution. Instead the Constitution states that: “This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby; any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.”—Article VI, Clause 2
