We have amendments written a bit over 200 years ago. The text is there, guaranteed authentic. All of the debates over the text are on record to give us the intent. Various publications by the writers further help give us the intent. Further legislation and court decisions by the writers give us precedent.
It really can’t be any clearer. However, you’ve seen we’ve “interpreted” it successively over the years so that to re-write it using the interpretation it would result in a completely different document.
I give it max ten years before any new amendment is reinterpreted so that the plain text and intent no longer exist in practice.
If people say they “believe in the Constitution”, they should have faith in its ability to survive and uphold the will of the people and states through statism like obamacare and the Roberts decision.
So, we need to amend the Constitution to remove the power of Congress to tax our behavior. At this point there is no Constitutional limit to tyranny.
