I think this piece is
I think this piece is completely wrong-headed, and I think I can illustrate why by comparing with something similar that happened in the recent past.
Think back to the shift from film cameras to digital cameras. There were epic, fiery debates online, on various forums, about film versus digital. There was certainly resistance to digital cameras from some quarters, and there were some folks—a relative handful—who never gave up shooting film. And nobody forced them to. Some of them are still shooting film today and waxing poetic about all the reasons why they love it. (Hint: Kodak recently re-introduced Ektachrome!)
However, the vast majority did go digital and never looked back. It was cheaper, it was more convenient, and after some period of rapid technological development, it performed better. It didn't take long at all for most camera makers to stop producing new film cameras. (They sure did rake in the cash while selling everyone new digital cameras, though! It was party time for the camera industry, aside from Kodak.)
However, cameras (like motor vehicles) are durable goods with a long service life. All those millions of existing film cameras didn't just disappear. Well, I'm sure some were actually thrown away, because their market value went to almost nothing. You could buy them for a song on eBay. Most were just put in a cardboard box and shoved into the back of a closet and forgotten.
I'd say the major tipping point for digital cameras was about 2004. Now in 2021 you can still find huge numbers of used film cameras for peanuts on eBay, although not as "can't give em away" cheap as they were several years ago, and the supply of certain high-end and desirable models has dried up and their prices have become pretty dear.
I can't see any reason why the market of combustion cars doesn't go the same way. It's not going to be a problem of people clamoring for gasoline-powered cars and trucks and not being able to get them. It's going to be a market absolutely flooded with dirt cheap used vehicles that most people don't want anymore.
