>> And such measures can be pretty useless and only amount to rent-seeking. I did hunter education in Colorado with the Makhaira group. Some students were unable to hit an 8.5x11 sheet of paper with a .22 bolt-action rifle at a distance of 5 yards (which is absolutely pathetic for someone who thinks they can hit a deer at even 100 yards with a hunting rifle). These individuals were granted their credentials because they failed this exercise while not breaking any of the gun safety rules
Gun safety is the point, not marksmanship.
In this case the point is safe drone use. There have been incidents of people flying drones in controlled airspace around airports, which is dangerous. The FAA doesn't give a shit about some dude and his drone, they care about the safety of the general public. A simple course like this will cut down on the number of people doing things that endanger others.
