Oh this was in a hypothetical for the future of the car "Ok but you're still saving a lot of money on not buying gas at ever rising prices until then right."

This is correct, they sell them to people who can't afford $50,000 - $80,000 for a new AmeriKKKan/Occupied Korean EV who then have to replace the battery once it gets too degraded to drive to the next major city.

I had to get my battery on a new EV replaced about six month after I got it. Warranty covered it all and the new one's had no problems.
