it's not convinient to fully disable charging at home, a lot of folks will revolt. and if you have people charging their cars at night, you always have a chance of swapping a worn out battery for a good one.
Of course. But if you know you don't really own the battery, and the swapping capability is in the price it is a non-issue. We already have something similar here, in Australia, for swapping LPG/propane gas bottles. You can refill if you want ( it is often cheaper) or swap with a full one. They are all dated so they also have "use by date"
And propane tanks are much cheaper than a large pack of litium batteries. Not worth it to steal a couple of dollars worth of metals from a propane tank, but the batteries are a large percentage of the cost of an electric car.
