Not sure if your're repeating FUD or not. But, I hear the argument you refer to quite a lot.
What I don't understand is why? This is an easily solvable problem - in fact. what if I told you your battery would always be "new"?
Use the propane BBQ example:
We have no problem buying a BBQ with a BRAND NEW propane tank(empty) only to take swap it for a full tank so that you can grill a few burgers. That tank you swapped for is not "NEW", but it is full, and it is certified safe and viable. It performs just like the new one you just bought and "gave away".
Look at fork lifts - same concept. These tanks are built to last, and are inspected to certify safety and reliability.
It's no different for batteries - I'd argue it's even better with batteries because on-board BMS can track usage and allow the energy supplier to swap out bad batteries when there is a problem detected. The end user will be assured a quality, and never have to worry about having to replace arguably the most expensive component of their vehicle. The energy suppliers are way better equipped to work with the recyclers en-masse to insure discount replacements and everyone is safe and happy.
My point is, this is an easily solvable problem, and nothing new. Both economically, technically and safely.
