The comments here miss the point. Sure you can’t cash out all your stock at once without serious effects.
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
