It’s an interesting idea, but I think you’d ultimately have to leave the union to implement it because you can’t restrict freedom of movement within the US. I think there are other potential solutions, however. Finding ways to create incentives for not speculating on property, huge taxes for vacation homes, etc. may work. Though it’s dangerous because you might get something that sounded good at the time but turned out to be a disaster like Prop 13.
