One thing that puzzles me about FAA registration as it applies to Phantoms. As I understand it, you can't even get your Phantom to work until you've registered it with DJI. Presumably, that registration links your Phantom's unique registration number with your name and address. This means, surely, that if your drone falls onto someone, etc, all the authorities have to do is contact DJI and they'll know who the owner is. So wouldn't it save a lot of money if the FAA only required registration if drone owners aren't registered on another database, as Phantom owners are?
