“If you’re in the club, you’re above the law.”
...and President Trump is not part of the club.
He was, but then he broke ranks.
Oligarchs and billionaires (Trump, Musk) belong to the Global Elite. They're above the law and entitled to a luxurious life -- provided they don't threaten the System. If they do, then the Global Elite unites against them.
A billionaire can easily crush a lone worker. But a billionaire cannot easily oppose a thousand other billionaires united against him.
