That would be virtual bleeding (which could be the case though), but if you bleed real money then somebody else has to receive it. If you hold a stock money doesn't come to you (except as annual profit distribution but that is a different issue). I read the fees for borrowing a stock for shorting are coupled to the market price (not sure). So if you fund lost a few billion real money (so they have to sell other assets to pay that) then somebody else has to get these billions now.
