But it conflicts with part 107 being used for all sUAS flights.
I can use a regular camera without needing yet another license to use it even if I'm using it commercially to sell a home. Now maybe I can't get that great roof shot with it, unless I take a possible liability in getting it, which makes the drone suitable for that purpose. But being only 20 feet up to get the shot is not going to poke much of a hole in the NAS, other than the verbage about the airspace above the property, anything above the blades of grass.
It's not the camera - it's the purpose of the flight. Just like you can't go joyriding in a Cessna and argue that you shouldn't need a pilot license because you are just taking photos.
And the commercial application is determined by yet another government agency to which I would be enlisted, most likely, and not the FAA per se. The FAA doesn't determine the commercial use, but rather a business license or some other paperwork entitled from another relevant agency.
You still don't understand. The FAA requires that you have a Part 107 to operate a drone - unless you fall into the special exception carved out by Congress to protect the model aircraft community. That exception requires your flights to be entirely recreational.
