Then what you are talking about is unwinding the derivatives markets, which goes into the 100's of trillions of dollars. To stop all forms of profiting from falling share, commodity, forex, etc. prices, we would need to scrap all short/long instruments. To do that would mean the utter destruction of the financial system as we know it. That will happen in due course due to the greed for more debt, not the current and any future short selling practices they manage to dream up.
