The advice isn't about reducing the number of Teslas. It's about helping someone get out of owning one. Also, that money doesn't go to Elon, it goes to the seller, so to some people, they might consider that part a wash.

If everyone wants to sell and nobody wants to buy, the used price will go down.

If used teslas in good condition are dirt cheap, there's no point buying a new one.

If nobody wants a new Tesla, there are fewer Teslas entering the streets.

If enough people try to get rid of their Teslas the Used value will crash and bring the New value even further down.

That was observed when Elon in his brilliance secured the Hertz deal and then slashed new Tesla prices. Leaving Hertz no choice but to dump their inventory.

The sell off from Hertz hurt the used value because it was a large supply of "We just want out, we already lost money on these"

I read it as a funny, polite, "fuck you". It's only going to piss someone off who bought a Tesla as a sign of status and is still a fan of Elon Musk. Everyone else will see it either as helpful but misguided or will get the joke.

It may reduce new sales

Cars are worth what someone is willing to pay. More used cars on the market means lower prices means fewer new cars are purchased. The biggest drop in value on any car (bigotry aside) happens at mile 1 when you drive it off the lot. But manufacturers love scarcity when there is high demand, so some manufacturers explicitly forbid buyers from selling their cars (Tesla and Ferrari are the only ones I know of, but there may be more.) If you want one, you must buy it new, and you better buy it quick because it won't last. They don't want buyers leaving the lot and shopping around, they want to create an atmosphere of panic and exclusivity.

Fortunately, they cannot enforce the requirements that you don't sell your car. What they can do is refuse to sell you another one, which Ferrari is famous for doing. With Tesla, if you're selling because you don't want to be associated with Nazis, you're not going to care if the Nazis won't sell you another car. Yes, you're probably selling to another Nazi, but most people cannot afford to simply abandon or scrap a functioning* car on principle. Selling is the next best thing, as it undercuts the aura of scarcity, drives the price down, and reduces the number of new cars sold.

Previous owners that gave money to Musk can distance themselves from him, while new owners that believe Teslas are good can buy one without giving money to Musk.

I'm in the market for a car and there is an amount of money I would spend for a used Tesla despite the potential for vandalism etc. I don't think there is an amount of money I'd spend on a new one
