Although many don't see it, America leads in freedom of personal aviation. I can use my aircraft just as I use my car. I have proper FAA licenses and medical certificates. I am instrument rated and can fly with the same rules as the airlines. I can also get in my plane and go camping at a remote strip or visit a restaurant in the next town's airport without requesting permission from anyone just as I would with my car. If I fly into big central airports following the same rules as the airlines then I can and do coordinate with the proper FAA officials. My use of these facilities is fully funded by taxes levied on the aviation gasoline that I burn n the plane. The idea here is that as a free American I can choose my mode of transportation within the nation's transportation system on the same basis as anyone else, private or corporate. For the most part, my aircraft is like my car.
With a switch from costs coming from taxes on aviation gasoline to "user fees" for various specific operations and a switch from a government control system to a private NGO the freedom to use an aircraft much like a car for personal transportation will mostly disappear. This is exactly what has happened in (e.g.) Europe where(for example) fees for each takeoff and landing effectively stop practice at small airports.
Then a governing board that will inevitably be dominated by the airlines will set the rules so that those pesky private aircraft will be effectively gone.
If you like this idea, then please accept the same for our highways. Each time you drive to the store for some milk, every time you take a weekend at the lake, you must first file a "drive plan" with a corporate board run by the trucking industry. Then you will give a credit card number so that your driveway exit, road use, and parking use fees will be automatically paid for the trip.
And if you think that this is tin-foil-hat stuff, please look at the rules for private aircraft in Europe and the rest of the world.
This is the death of one more freedom that we currently have in this great country.
