The purpose of stock markets is to find the "correct" price for a stock. To that end, it needs to be possible to express both bullish and bearish views. However, doing the latter is already more difficult because in order to short the stock, you need to borrow it first, and you need to pay for those borrowed shares for as long as you keep holding them. Furthermore, those borrows can be pulled at any time, forcing you to cover at the most inopportune of times. There are also things like Reg SHO Rule 201(b) ("Uptick rule") that further complicate shorting a stock. Regulators have even been known to ban short sales in certain names outright like they they did for financial stocks during the 2008 financial crisis.

If anything, selling short needs to be made easier as it represents an essential corrective. And this ultimately serves the greater good too as it ensures that the price of a stock is correct and investors don't overpay, which will inevitably lead to losses for them. A good recent example of what happens otherwise is Wirecard. In 2019 the German BaFin enacted a ban on short sales in the stock of the company after reports had been published that were essentially accusing them of fraud. In the end, those reports turned out to be true, and the company collapsed less than 18 months later. The stock fell from over EUR 150 to virtually zero and investors lost pretty much everything. They should have listened to the short sellers rather than fight them.

There are also no "easy profits" in short selling. They only make money if they are right. There are people who have been calling for the immediate collapse of Tesla for the last decade or so. Others have been trying to short Amazon, Google, Apple, Microsoft, because they think that these companies are completely overvalues. Most of these people are probably bankrupt by now.

But GME isn't any of those companies. They are a failing brick and mortar retailer that is boxed in by Steam on one side and Amazon on the other. They have repeatedly attempted to transform the company over the last decade without success. The fact that their plan is to launch some NFT market place, a field in which they have no experience and that is already crowded by established players like OpenSea, demonstrates how much their management is completely out of ideas. And if the shorts make money from the GME stock, it just means they were right.
