Walking out on debt and treaty obligations don't make those obligations go away. It means that fulfilling those obligations places a harder burden on the states remaining. Also, when Florida appropriates federal property it could be accurately said that said property belongs to all states and it's being taken without compensation. That's how.
Too complicated. The court cases would never end. Never.
The same can be said about any legal matter. But convenience alone is no reason to toss the law out the window.
Your attitude is scary: Nation-state above all else, including individual freedom.
No, my attitude is that ALL states are equal, ALL states have the right to be protected by the Constitution. Your attitude is that only the leaving states had any rights and that the Constitution existed to give them a club to beat up the remaining states. That, to me, is the scary position.
You need to re-read the Bill of Rights.
You might try reading the whole Constitution.
Then seek a legal remedy. Nations sue nations all the time.
ALL states have the right to be protected by the Constitution.
And ALL people have a right to be protected by the Constitution unless they give up citizenship here for another country. Then they are at the mercy of that country's rules, or lack of. Should these people be forced to continue to pay US taxes because we need the revenue?
This country wasn't founded on the state or nation. It was founded on For the People, By the People and Of the People. If some of those people choose to walk, then so be it.
That, to me, is the scary position.
Individual freedom is scary? That says a lot about you.
