Tell us how. I don't think the guy you are replying to actually thinks that the dozens of multibillionaires out there are holding their billions as cash that they could hand over to Musk tomorrow. Their wealth is held in assets with varying levels of liquidity, and, most notably in the case of stock, trying to convert them to cash would decrease the value of the remainder. But if Bezos wanted to get his hands on 10 billion to fund Musk, why could he not? (Ignoring the fact that he has his own aerospace thing going on.)
