And these billionaires could still buy a second house in Cabo with a helipad using what is remaining

Important to remember just how much a billion dollars is. Even a billionaire who has only $500m after giving away half would be able to buy a dozen of those properties. A multi-billionaire could potentially buy hundreds of similar properties with money left over. A billion dollars is a TREMENDOUS amount of money.
