The whores on the hill will do anything to maintain their lips on the teat of the 'public'. If the public likes added medical requirements for Ga pilots, then liberty be damned, there will-be-something-done. If the 'public' wants GA shut down with all airspace under positive control, then eventually that will be done, and you can just go sit in a corner and whine about your freedoms.
Look, the train is on the rails, and it's got a head of steam. ADS-B is the biggest airspace grab in history by far, and it's already something that you'all just assume you can do nothing about it. Sure, big brother needs to know who is in the air, where they start, where they go, how high and how long they fly, etc. If it's not something that the 'public' does like drive a car, well then lets shut it down! You don't NEED to be in the air, flying your own private plane, going where you want without asking permission. Oh hell no, only car drivers like me are permitted, all others in planes, well you just have to give up your liberty. It's for the children!
What a sad, sad state of affairs that everyone now takes this stuff for granted. Sad in so many ways.
