You see similar longevity in Teslas with hundreds of thousands of miles on them.

17 million new vehicles are sold per year in the US. I would argue EVs are not yet sold at a volume sufficient to drag the average new vehicles sales price up much beyond the $48k it’s currently at. Cars are just more expensive, interest rates keep rising, and wages aren’t keeping up.
The batteries have been reported to deteriorate to subpar performance at a rate similar to that of a part on an ICE vehicle that would be a consumable [1] (also shown by the links you provided).
For example, around the time an ICE car might ordinarily undergo a major service (e.g. timing belt).
I was speculating that the fact it deteriorates and isn't an inexpensive consumable, may be why people are choosing not to purchase them outright.
