With what DeSantis is doing here it wouldn't surprise me that if he had the power to nationalize Disney just on a state level I bet he would as he's that vindictive. Luckily he can't. I'd laugh like hell if he really pisses Disney off and they decide to shut down all of their FL parks and move them to like SC or GA. However this won't happen as it would be too expensive and take to long.
Never say never, though it's highly unlikely.
Of course, politics being what they are - this is only yet another storm to weather, especially if the governor's wishes are overturned in court or gets voted out of office before anything becomes enforceable and the next governor decides to pull the plug...
