That's not the point. If Jeff Bezos wanted to spend 1 billion dollars today he could. Like maybe he couldn't walk out of the bank with 1 billion dollars in cash, but all he would need to do was sign a piece of paper and that 1 billion is on its way to a new owner. That 1 billion on its own is more than enough for you and your family to live extravagantly for your entire lives, and you still wouldn't touch half of it. After spending that 1 billion dollars, he's got 184 more. It may not be cash, but it's value that can be traded, spent, or used as collateral.

The form that this wealth takes is irrelevant. What matters is that if it were redistributed, it could change thousands or even millions of lives, and instead it serves only one person.
