The Universe is Hilarious: Drone Registration
So yea, registering your drone with the government is stupid and complete bullcrap.
You give them your name, address, and credit card and they hand you a certificate.
That is all there is to it, no drone required. I blanked out my registration number because I want people to work for it if they want to know what it is and allegedly it should be easy enough to find.
Enjoy your newly found sense of safety and security when it comes to drones!
