"Shorts can do damage far faster and easier than longs. It always easier to destroy something. Pumpers create value, Bashers liquidate it."
That is where you are wrong. There is no value created by pumping a stock. When large players pump up a stock, they create a bubble. These bubbles are not backed up with fundimentals but instead on fake demand. Eventually the bubbles (all bubbles) will pop and the stock will fall. By this time, the pumpers will have exited the stock at the inflated level and taken all the retail investor's money with them. Being that they are long, an uptick rule will not prevent them from taking your money.
Then you will blame the shorts who had nothing to do with stealing your money but were smart enough to see that the stock was being used to scam the small guy.
