Tesla can buy other companies with it's stock. Facebook's stock is basically Mark's personal currency. I understand that buying stock isn't straight up giving a company cash, but by pumping up its value, the shares the company is in control of are worth more. I also totally get how thinking people are this altruistic with investing is naive, and it's probably just fomo and short squeezes in a death spiral.
