That's absolutely wild, genuinely terrible, and intends something basically no different than what we already have. The biggest difference would be all of your conservative areas immediately collapsing without funding from liberal areas lol. I mean, your whole plan is basically just not having the United States anymore, and assuming that states will continue to play nicely with one another when they no longer have any higher authority to hold them to rules and regulations.
States already have different laws on abortion, gun ownership, taxes, and "personal freedoms". People can already move. This is just such a strange political take, I almost don't know what to say.
