Incorrect. Elon still controls everything he puts on his foundation, and when he's gone he will appoint people to control it. That is a fact. He can still sell those shares (without paying taxes) and diversify his holdings if necessary. He can invest in other companies using that money to help him achieve his goals. It is just a bunch of money that he can control in several ways. You just don't have great imagination, but Elon and his lawyers know what is possible.
