The comments here miss the point. Sure you can’t cash out all your stock at once without serious effects.<p>There is no need to sell any stock though to access insane wealth. I racked up a bill on that site worth 5% of Elon’s value and went pretty wild. Elon could easily tap into that wealth tomorrow with a loan from a bank backed by collateral from his stock without selling a thing. So he maintains control of his companies, doesn’t pay taxes (as he sold nothing), and can literally buy anything he could ever imagine without having any serious effect on his net worth
