One concern I have is that anything given to you by the govt. can be taken away.
And if it was taken away in whole or in part at a later date, where would you be? Nothing left to revert back to and a very steep hill to climb to reinstate your old laws.
The wording and meaning in such a bill would have to be unequivocal and not subject to anyone's interpretation or change without some sort of super majority involving every state.
