So how are mechanics going to solve the battery problem? Maybe replace dead batteries with used but still somewhat working batteries? But then after 20 years all batteries for that same model will be dead.

Or are you trying to say that poor people will be able to buy newer cars than they do now, because rich people will dump them sooner?

The batteries won't be dead immediately. These studies saying they last so and so long define "lasting" by still having more than 80% of the initial capacity (iirc). So for people who usually don't drive more than let's say 100 km at once most EV will still be totally fine.
