What you're saying should be absolutely correct, but in practice incredibly naive. First, I don't disagree the market and price discovery can benefit from shorting. But here we're talking about retirement accounts that are already long the stocks in question. There's no world in which the owners of those stocks benefit from them being lent out to short sellers, despite creative rhetoric to the contrary. If the shorters are right and the company is a fraud, it's STILL not in the interest of owners of stock in that company to lend their shares out. If anything, it's even MORE in their interest to NOT lend them out to be sold short, instead, they need all the help they can get to keep the price up so they can make a controlled exit themselves. Second, why, if a decrease in price is all just an artifact of shorting, and it is in fact a solid, profitable business with a bright future, can't this be easily countered by simply pointing that out and buying the shares at a discount until the market catches on and the price skyrockets back up? Because, unfortunately, it's much easier to just go with the momentum and jump on the shorting bandwagon, betting the stock will go down even more. Even if you tried to stem the drop, the short sellers can just borrow even more stocks and continue to overwhelm you with selling pressure. This dynamic plays out all the time in US stock markets, and this isn't even taking into account abusive naked shorting, which is actually kinda sorta illegal except even the rules against that aren't meaningfully enforced.
