What if an individual is interested in the history and traditions of the place where they were born and after studying it, decide that they would voluntarily like to sign the social contract exactly as stated in the US Constitution? That is, they accept the idea of the de jure law construct.
They take an oath and this oath acts as their signature on the document. They have only sworn to uphold the Constitution specifically and not the vast unconstitutional system as it existed de facto when they made their oath.
Have they not signed on to the social contract de jure while rejected it de facto?
