You make a lot of sense. The problem is some people are flat out against any rules/regulations even if they are for the betterment of the public.I'd like to muddy the waters a bit...and forgive my rant...it may seem off topic...but may make some sense...
Along with flying my drone, I'm a professional photographer and have been for the past 30+ years.
Do you have any idea how many people with cameras are out shooting jobs that 'should' belong to experienced professionals?
I see amateurs all the time shooting weddings, portraits, etc., without honestly fully knowing what they're doing, besides pushing the shutter button, and taking money for it.
They're not the least bit afraid, and should be. There's a lot that can go wrong, and a lot they're not prepared to handle.
I'm not saying you can't go to someone's wedding or event and take some good photos, and with today's technology. It's very easy to get a good quality photo, however, working to professional standards and charging money for it should mean that you will not just happen to catch a few good shots, but consistently deliver throughout the job nothing but first rate images.
Imagine someone setting up shop as a barber without a license...just a pair of clippers and a scissor...oh...I'll give it a try...I watched someone cut hair once...it'll grow back!
I have seen people with drones doing the same thing. I feel the FAA license is like door locks. Locks are for honest people. Those who are licensed should act accordingly. Those who are not will do as they please, regardless and not worry UNTIL they get told otherwise.
Sadly there's no way to stop it. People are driving without drivers' licenses, car insurance, vehicle inspections/registrations for a variety of reason as well, and until they get caught, they will continue to do so.
Your "door locks" analogy is spot on.
