You seem to be imagining problems that do not exist. The battery swap facility was for the Tesla Model S only, and the battery cannot be removed as if it was a Duracell. It needed to be disconnected with a specialized robot. Current battery packs are even harder to remove - even if "battery pack theft squads" were a thing, which they aren't.
