I see your point, but I fail to see how this addresses it. Drone operators who have caused those incidents you speak of are not likely to register, or adhere to any minimum safety standards. All this does is force people who already follow to rules to follow one more rule.
I sure don't have an answer to the drone problem, but this sure isn't it. Traditional model aircraft users should have been separated from the "drone" users years ago, but now they are all lumped in, and now must deal with misplaced knee-jerk reactions.
