Your belief is certainly reasonable. Over the years the Constitution has been made to say many things...and many things have been made legal which were once illegal and vice-versa.
Still, people have been very, very careful about changing the basic language, the basic forms, the basic checks and balances. I think that is as it should be.
Blackstone presumes an authority that is above the law. Lose that ... assert that man's law is "supreme" ... and the bedrock is at least disturbed, if not disregarded.
