should require the drone operator be a licensed pilot
I hope you don't mean the same type of pilot's license required for manned non-ultralight aircraft. I think there should, however be a separate license for drone pilots. There needs to be a set of rules and procedures, with a license test that requires you to demonstrate you know them via a written test, similar concept to a HAM technical class license . It doesn't have to be a huge barrier to entry, just make sure you know the rules. If you fly a drone without a license or you break the rules then you get a fine. The problem is that the FAA would take at least 15 years to come up with such a thing and the rules would be an arcane mishmash of 15 years worth of bureaucrats adding to them.
