I think you're still misunderstanding how this would work. So this battery swap setup is like the equivalent of going to the gas station. Basically, when your battery is close to being dead, you head to this place and get a fully charged battery. So it doesn't matter that the battery is used, you just keeping swapping batteries out when you need it. Sure it would be annoying to know that when you bought the car, it came with a fresh battery that would get swapped out with an older battery, but you would have bought the car to get into the swapping system since this is mainly for folks that can't do charging at home.
