Can't or doesn't... regardless, he isn't. I think his wealth is inflated. When he defaults on his twitter loan, lenders will sell their collateral aka Tesla shares, to make up the difference dragging Tesla down with it and eliminating a huge portion of his wealth and the wealth of people/shareholders invested in Tesla.
It’s almost as though he’s using that money to bully smaller people because they can’t afford to sue him. Which, in a shocking coincidence, is how Trump ran his companies.
He is not adhering to a contract, so that's the point he is making for some reason, and not the opposite. t was more of a joke, because he does hold some weird views about free market ("rules for thee and not for me", stuff like that).
