The thing about Herr Musk is that he doesn't really have all that money in hand. He is worth that much because of stocks and other intangibles. But ask him to put it all in cash on a table, and he can't. That's why he needed loans and other monetary help to buy Twitter. If Tesla collapses, so will much of his worth, and then what? He might lash out horribly or go quietly into the night. These are interesting times.
