@josh0 got it. Makes sense.
IMO if we can cause used Tesla prices to crash, that would hurt Musk. It would make it harder for current Tesla owners to trade in a used Tesla for a new one, and it would make people less likely to buy a new Tesla due to the threat of depreciation and/or social stigma. Tesla also maintains an inventory of used cars at all times, and if those assets lose value, the company takes a loss. These things can all compound; Tesla’s inflated stock price is based on Musk’s ridiculous claims of 100% growth forever; a few quarters of low or no growth could crash the stock price. Which would be, IMO, a good thing.
