I honestly have no clue what you're on about. There's nothing philosophical about this discussion - it's entirely practical. We don't want to get hurt by other people's mistakes, therefore we don't let people do things where that is a possibility without training or supervision by someone who is trained. You do not have the freedom to do XYZ when society has decided that if you attempt to do XYZ, measures should be taken to stop and/or punish you. The fact that you have the ability to do XYZ and that the authorities we have delegated to ensure you don't do XYZ are doing their job well is entirely besides the point. People don't want to get hit by a car, so we've collectively agreed to require that all drivers pass an exam that proves they know how to drive safely enough to bring the risk of them running someone over with a car to an acceptable level. The general freedom to drive a car does not exist - we've collectively limited it to only those individuals, who pass our standard. Similarly, everyone does not have the right to build their own airplanes and fly people around in them, because those people could get seriously hurt - we have limited that "freedom" to only people who have proven that they know enough about how to build and/or fly planes to, again, decrease that risk down to an acceptable level.
