I tend to look at all this like driving.
100 years ago, as the Model T really brought automobiles to the masses....you didn’t need a license, you could drive anywhere the car could go, and there were few traffic laws. It became chaotic, and resulted in some bizarre laws at first. Up until my high school years, there was still a law on the books that said before driving an auto coach upon the square you must stop, announce your intentions, then proceed with caution. If you spooked any horses, you were responsible for any damages.
So, I see our greater civilian use of the airspace like this...it’s in its infancy. It will be painful to grow, but look where our roadway system is today, with vehicle registration, licensure, extensive system of traffic laws, Drivers Education, on and on and on. We’ll have to get there with the airspace as well. Just think if flying cars ever become a reality. Imagine if someone built a scaled up drone capable of carrying 4 adults, flying for 500 miles at 100+ mph, and only costs $18k. Easy to learn to fly and pretty safe. Everyone ditches the road car and buys the flying car.
