Jefferson and those guys also did not think that document would be worth crap after a generation or two. They thought new revolutions would be needed every so often.
The same would be with our states should the federal government detach itself from the Constitution and use military force to overthrow state leadership. They will need other states, and even other nations, to side with the states in the next few years, not decades.

Jefferson had nothing to do with the Constitution and did not understand it much or accept it. Marshall and Hamilton are the authorities on the meaning.
