Drones are just too easy to fly to an airport. Registration won't fix that, unfortunately. I literally just had a Phantom 4 shipped to my house (the hard part was figuring out which CC would make a payment to DJI). I took that thing out of the box, figured out how to send the message to DJI to activate the drone, and within an hour, I had that thing rocketing straight up toward final approach course for 19R here in MKE. I respected the 400 AGL limit, but any user could choose to not do that because my village is "pretty far" away. You could very well hit an airplane in minutes and requiring registration will not help.
IMO, the drone industry is great and we will benefit from a limit on actual regulation. What we need is more protection/detection. The question I have is how close are we to TCAS-like detection for drones. They are technologically-advanced machines and surely we can come up with something that can detect the presence of a machine that uses stabilization and freqs for control. Heck, there are companies that are developing anti-drone technology for spacial use. That could be incorporated into aircraft.
You'll find that the phantom won't fly within 3 miles of an airport runway- and, comes factory capped to 120 meters (~380ft ) above take off point. You can change the settings to allow 500m though, which at the 3 mile ring would still make it a threat. Rumor has it that the "3mile" NFZ actually expands with altitude though, so maybe they have provided decent FAP protection. I haven't tested it personally though
