Nah. Seize his assets, but make him stay here. Make that Nazi bastard experience life the American Way™ - living paycheck to paycheck at a minimum wage job (cause the moment his net worth guess to zero, his political influence does as well - another trademarked advantage of American living).
He'd still be a celebrity, a couple of talk show invitations and he'd be better off than the bar majority of Americans. Not to speak of other opportunities he'd have.
Zero assets? Yeah, I really doubt that. He's not smart. And his popularity? You think any of these sociopaths in power actually like each other? Not a chance.
The moment there's no chance of material gain by sucking up to him, he'd be tossed aside.
I really wish we'd stop hero worshipping the most worthless fools amongst us.
So here in Italy a few days ago, a small mountain town got invaded by 10000 people because a random tiktok influencer posted that she was there skiing.
Never underestimate people's stupidity and attraction to celebrities.
I really don't think it'll work. Americans absolutely love their celebrities. Elon musk will never be poor, people will just give him money for existing.
