It's very expensive to move the business that owns the assets, and then you need to ensure you don't become resident again.

Once the money moves, it won't come back to where it can be grabbed.

That's why the USA has exit taxes when giving up green cards and citizenship.

But the business didn't move. Meta not moving to FL, and Prop 40 doesn't give any reason to move it; it's a tax on the resident, not the business.
