You aren’t answering the question. If a state (the people of that state) isn’t free to go, are they free?

Maybe I don't understand your question. What do you mean by "go"? There is no Berlin wall here. Any or all can "go" whenever they want so long as they can find another country to accept them.

If by "go" you mean stay and secede from the USA, then my prediction is that the rest of the USA will prevent it, by force if necessary.

The USA purchased Louisiana from France. Does that mean that the USA can now sell Louisiana to another country?

These things aren't going to happen. Too many people are too patriotic. Like it or not, we're bound together, at least in our lifetimes. Some will leave, but most will stay and try to turn things around.
