SEC Banning Short Selling

Correct me if I’m wrong, but it seems like HF’s can’t collectively pummel a stock too far below what its really worth for long. Eventually, one of the funds will crack and buy low, or else non-HF money will start buying and all those naked-shorts are left competing for the rapidly appreciating shares. What’s wrong with letting people who play a risky game get punished every once in a while?
