Good point. A survey of our history would find that the vast majority of abuses of liberty have been on the state and local government level, not on the Federal level. Infact, through the 100 years between the civil war and the 1960s, virtually every "States Rights" argument was in reality an argument for the right of state governments to ignore individual rights and liberties guranteed by the Federal Constitution.
That history of abuse and over reaching by some states has deeply damaged the concept of states rights.
