Our last hope for justice are the courts. Musk has three major trials in October, the 420 "funding secured" trial, some sex discrimination or bullying trial, I think, and the twitter trial in Delaware Chancery court.
The Chancery is our best chance, as they don't play. And Musk has already caused a rule 11 breach by signing statements that his own evidentiary submitions prove false.
I hope the courts fine him a few billion for his antics, and maybe ban him from being an company officer for 5 years. That's the only punishment that would be meaningful for a man like that. Specific performance, alone, would be a massive win for Musk. He needs to get fined hard, too.
