Why not? It's the basic *legal* contract between you, and your government. It is, in all practicality, the heart, and the soul, of the nation. In short, the Constitution is the nation, and anyone who seeks to displace it with *anything* else, is by the terms of said contract, "levying war against the United States", or, in short, comitting treason...

I look at the Constitution from the same angle as you have posted.
It is a contract among, and between the states to form a new political entity, the general government.
There is no way that any sane entity would give the opposite/formed entity in a contract the sole “interpretation” and modification power of that contract.
