Do you think drones used by private citizens should be registered with the government?

What is a drone, remote controlled airplanes have been around a long time. Typically there are ceilings ~5,000 feet AGL or so that they are not allowed to fly above, or in restricted airspace. Any aircraft would need to be registered on those facts alone, I see no difference between a remote controlled airplane and a piloted aircraft.

Drones used for commerce is a different matter and will need to be regulated.

Hmm....I hesitate to register them mostly because it would be impossible to enforce, there just too many out there.
However I do feel there are serious privacy issues associated with there use.

I'm surprised that it haven't happen yet. Another way for the government to tax something.
