There are things you say that just expose how clueless you are about a topic. Have you ever seen where someone pulls out 40 billion dollars at once to buy a thing? How do you think he would have 40 billion in cash lying around? I don't even think any billionaire would pay for a thing worth 10 billion at once from his own money without looking for other investors. What world do you live in?
A net worth is all you are worth, not how much money you have in the bank. All your assets minus your liabilities is your net worth. It doesn't mean the money you have in the bank. Except you're a drug deal syndicate or another criminal organization, there no body that should have 40 billion in cash lying around. The fact that a person is worth one trillion doesn't mean that worth is in money, but it's his assets. His shares and every other asset.
I do, they did not pay with cash, they paid with stock, or they paid with loan, not with others money that they went around begging. And that is exactly what I am talking about, he has networth, not money, that is literally what I have been saying all along. Networth means nothing, tomorrow Spacex could worth 1% of its current value, there is no guarantee, how would we know? Maybe he goes mad and crazy and does something stupid and suddenly he worths nothing? How could you guarantee that?
Walmart for example has a family behind it, they can all go mad, and Walmart will still be Walmart, or Warren Buffet could die today, and Berkshire still has that money and won't go down that much for too long (may go down a bit on his death for emotional reasons but will recover).
Elon does not have that, all he has is worth his "super stardom", the moment he dies, none of this worths anything, not tesla, not Spacex, because he is the marketing, not the company, him. Space even more so than tesla, tesla could still survive, but Spacex won't. So his networht in theory is a lot, but he worths nothing IMO.
