Yet you and I agree that Congress (via the FAA) may regulate his activities if and when those activities have a substantial effect on the interstate commerce (commercial flights) that Congress is constitutionally regulating.

If he doesn't leave the ground of his property, the FAA does not regulate his piloting of an airplane. Hence, your example is false.

"If he doesn't leave the ground of his property, the FAA does not regulate his piloting of an airplane."

He can fly all over the state and the FAA as no authority. It is only when he has a substantial effect (ie., flying into controlled airspace) that the FAA gets involved.

So my analogy is valid. Actually, excellent.
