Secession will be a a natural by product of a total economic collapse. Some states will just simply refuse to go over the fiscal cliff and leave the union. They seceding states will reform as a new country or just be independent sovereigns. Either way they will be done with the imperfect disunion.
Both cited Montesquieu when it came to how a nation that expected to span a continent could be ruled other than by coercion from a small, centralized, consolidated government.
The answer was to create a federated republic, IOW a republic composed of republics.
Henry assumed consolidated tyranny in the near term. Madison denied that could happen as long as there was a senate of the states.
Maybe all of the States should just secede from the District of Criminals.
Some people will just simply refuse to hand over their stuff to the feral government and will do their very best to kill anyone who tries to come and take it.
