Show me the line that says it has to have such a line. This! I may be an atheist European very fond of our socialist democrat government, but the bottom line is: the government should regulate what the population thinks should be regulated and not a bit more. If I want to fly and apply myself fulltime, I can have my flying license in a month, being free to roam most of the national airspace (as long as I tell some people where I'm going, so they can help me prevent collisions). I would surely expect it to be the same in the US: everyone has the right to travel by air, provided they adhere to a minimal set of guidelines to prevent them from endangering themselves or others in ways obviously directly related to the 'flying' itself (and not to e.g. the suspicion that someone might have a 1% higher change of using the plane for a terrorist attach).
