You are 100% correct. It was meant to be funny, not factual though...
If you took a job from which you had not the right of resignation would you believe you had any power to demand any sort of consideration on that job. If you joined a gang which demanded lifetime membership and from which you could not resign on pain of death would you be able to demand any consideration from the leaders of said gang, would you be able to say what you would and wouldn’t do in response to their demands? Think about it, the South Carolinians who agreed to join the United States of America never thought for one minute that they DID NOT have the right to opt out at a later date. If they had thought so they never would have agreed to join. Oklahoma will meet with no success for the same reason, they have no right of secession so they have no actual rights not granted to them by the Federal Government, the exact opposite of what the Constitution says. States rights is now a dead issue, this will never change short of an actual revolution.
The recent SCOTUS ruling concerning Guantanamo prisoners would seem to indicate that allegiance to the Constitution is as dead as the Dodo.
