Nobody with a new battery is going to want to swap it out for a old, potentially degraded battery. But everyone with an old battery would be happy to try to swap their way into a new battery.

Great, this old schtick again. News flash: nobody cares whether or not they own their car battery. With modern BMS systems, you would basically pay by the coulomb.

But yeah, I think this particular ship has sailed, at least for the near-term future. Huge missed opportunity. Refueling an EV should be as quick and easy as swapping out a BBQ propane cylinder -- which is also something you don't care if you own or not -- at your local convenience store.
