If someone tries to redistribute land, it could get very ugly fast.
I doubt that's going to happen, not least since the supreme court ruling seems pretty specific that they can't. That being said, there's a lot of unanswered questions with regards to things like taxes, infrastructure, and law enforcement, in what's probably one of the most heavily armed regions of the world, which is full of little oddball communities trying to get away from everyone else, and which just so happens to be mountainous.
My gut feeling tells me the native tribes are not interested in trying to administer this region, and that everything will stay exactly the same but with stupider paperwork.
