Amusing interpretation at best. Tell me, how would you react if a republican had said that? Here is an interesting example of the way things could be done.

In order to buy a package of Pseudoephedrine ( a very effective antihistamine), I need to show my driver's license or other government issued ID, and then sign for it. Also, I am allowed to purchase only one package. This is supposed to prevent bulk purchases for use in making methamphetamine. There is a weakness however, I can just go down the street to another pharmacy and purchase another package. if i wanted to set up a meth lab, I could go to to every nearby pharmacy every day and buy enough to stock the lab.

I suppose, that governments, federal, sate, or local could require that hobby shops and toy stores require drone purchasers to show an ID, read a safety brochure and sign-off on having reads it. It would not do a whole lot of good, since most jerks will just ignore it, but at least it will make some people think and slightly reduce the number of unsafe incidents. Then the jerks can be punished more severely.
