Agreed, this situation is uncomfortably similar to a number Trump crises. Much of our legal system is based on norms and good faith, which a sufficiently motivated and powerful psychopath can pervert to their advantage.
I have no idea what will happen here. Musk is clearly in the wrong both legally and ethically, but I suspect he will weasel out of resbonsibility for the damage he's caused. That alone will be bad enough, but the much larger risk is that it opens the floodgates for slightly less powerful scumbags to flout the law.
US law and democracy are shakier than I've seen in my lifetime, and Musk is actively taking a sledgehammer to a piece of that foundation for his own greed and whim.
