@KathyReid shorting doesn't destroy value, it indicates a high confidence that value will be destroyed, and that can influence others, but if it was enough, tesla and others would have been dead in the water long ago.
It's also both hard and very risky, to tell short, someone needs to lend you shares, you pay interests on that, and to avoid the risk of being unable to give them back, if the price increases too much for your margin to cover it, your position is liquidated, taking all your money.
