Your idea only works if you believe there is a global conspiracy of businesses and scientists who all agree to embargo research into cures, and who are all willing to forgo any profits on the cure while also recognizing any scientist and company not in their conspiracy could wipe out their profits at any time.
Additionally, I’d think that the small constant corrections of short sellers helps avoid most large cost corrections later.

We show that stock prices are more accurate when short sellers are more active. First, in a large panel of NYSE-listed stocks, intraday informational efficiency of prices improves with greater shorting flow. Second, at monthly and annual horizons, more shorting flow accelerates the incorporation of public information into prices. Third, greater shorting flow reduces post-earnings-announcement drift for negative earnings surprises. Fourth, short sellers change their trading around extreme return events in a way that aids price discovery and reduces divergence from fundamental values. These results are robust to various econometric specifications, and their magnitude is economically meaningful.

Short selling is still an essential part of markets and price discovery, it’s not really that hard to understand why Elon is against it.
American culture is largely descended from Anglo-Saxon culture, but that doesn’t transitively mean that all American culture is now Anglo-Saxon. The pockets of non Anglo-Saxon culture are not recent additions to black culture, they’ve been intact and distinct throughout their history. The Gullah people are American, not an expat community.
