Both a sensible business move and the right thing to do. If they could magically roll up the entirety of WDW and relocate it elsewhere I suspect they would.
It wouldn’t be the same, with all of WDW’s history, direct involvement of Walt and Roy Disney, weird systems (underground garbage vacuum service, etc). But America has a lot of unoccupied land, and most states would be happy to give Disney significant leeway in exchange for long-term guaranteed taxes, jobs, and tourism.
One thing is certain: the next FL governor after DeSantis will have a gigantic mess to clean up.
