I'm with you here. There's always the component that the government will tax everything they can, but having a licencing and regulatory demands attached to potentially dangerous activities is important. Driving, shooting, sky diving, food vendor, day car, and so on. Considering the amount of damage (and death) that gets caused by people who are unlicensed and still own/drive vehicles, there might even be an argument to make licensing part and parcel with ownership, like firearms.
