There is a question on whether that consent can be withdrawn - and on the basis of that ambiguity the statist judges would surely rule that any attempt to regain that land would be illegal unless the Federal government consented to release it.

Any judge would agree with that. You can't have a state suddenly deciding to take over all courthouses, post offices, and military bases with its borders. As it is, though, some closed military bases have been turned over to states and cities.

. . .a state suddenly deciding to take over . . .

Nothing in my post said that the states could 'suddenly decide to take over . . ." anything. They formally deliver notice (requiring an act of the State legislature - never a 'sudden' thing) that they no longer consent to the occupation, and then pay compensation (requiring money from the State - never a sudden thing). This is a formal, legal procedure that is - as I read the words - Constitutional.

Your post said, "You can't . . ." and I interpreted that as the generic "you" as in "One can't . . ." But if it truly were up to me - and I am a strict Constitutionalist - this would happen quite a bit. I wouldn't start with miliary bases and courthouses, but there is a lot of land claimed by the Federal government that they are not using responsibly. I used "National Monument" in my first post because - unlike National Parks, National Monuments are off-limits to ordinary citizens. National Forests were described by a Forest Ranger as different from National Parks because the National Forest was considered a resource area and it was the responsibility of the Park Service to help develop them economically. He was asked how many logging leases they currently had authorized . . . and the answer was none.

But my primary contention was that if South Carolina had followed, or at least tried to follow, what the Constitution said, then the War Between the States might have been avoided. The Constitution is our contract with ourselves and I always look to see what it says, particularly with the view of finding a non-violent way to resolve issues.
