I imagine they must start out doing it like this until they test usage, etc.. Who knows how people could take advantage of it otherwise. It would prevent a possible initial problem of a ton of battery packs just building up in one location. They'd want the first users to to be regular users, and by keeping it to those who it works for, the service will be available faster + once again they won't need to build capacity to store a huge excess amount of of battery packs on location.
