re: How is this different than a state leaving the US.

Ok.... so apparently all you understand are off base analogies that make no sense at all.

If you head to your local Kroger today, you purchase a $100 brisket. You leave the store, and shucks you forgot the brisket! You don't go back though you're busy, you don't return the next day either. You wait 30 years. The kroger is no longer a kroger, it's a dippin dots. That's right 30 years from now dippin dots have finally made it, and in fact that's the only store left in the world, dippin dots owns everything, they told you it was the future. Now you decide you're going to take your $100 worth of merchandise back, it was yours after all. That's called theft, plain jane, dipping dot theft. You are going to jail, there's no justification and you will be a convicted criminal to be sent to dippin dot jail.
