Earlier quoted context omitted.
Short selling is not a fundamental activity. Short selling should be the thing that is illegal. None of this nonsense would exist if it weren’t for the absurd nonsense that is borrowing a stock, selling it, waiting for the price to drop, buying a stock, and giving it back. Short selling is absurd. All options trading should be banned by the SEC.
What you are suggesting is a one-sided market where prices can only go up and there is no restoring force. That's dumb. What's worth knowing is that immoral conspiracies among short sellers are incredibly rare. I challenge you to find a documented case. By contrast, there have been many, many pump-and-dump sell-side scams, and without the short side there would be many more.
Aren't there other ways to take a short position on a stock without actually short selling it? Like buying a put option?
