The benefit to swappable batteries in a commercial fleet is that you own all of them.
For private use, it is far more difficult. The battery is the single most expensive part of the car- who wants to drive off the lot, then two hours later trade that expensive part for one that is heavily used?
Unless the dealer or manufacturer runs all of the swapping stations, and the purchase of the car doesn't include the battery, the economics are terrible.
OTOH, if the consumer isn't paying the full price to own the battery, then the economics of swapping goes way down unless the consumer pays a hefty deposit on the battery.
Then, private sales become harder as you probably want to be able to authenticate that battery is what it is supposed to be, and not some third party knockoff.
But if you can't swap to a third party battery, the vehicle becomes worthless once those batteries are phased out.
Swapping vehicle batteries has been tried before and abandoned (I think in Israel maybe? I forget) because unless you are operating a commercial fleet where you are willing to invest in buying the extra batteries and owning them yourself (or signing a big fat contact with a manufacturer) it just doesn't make sense.
I think the swapping model is working for taxi drivers in China, but it's a model where the vehicle owner doesn't own the battery, it's more like a lease model. Thus if you do accidentally get a bad battery in a swap, you don't take any loss (other than inconvenience), you just go back and get another one. Matching demand and supply might be a bit tricky, but it's a steadily growning industry in China:
