I think these should be regulated, even though I own and fly several quadcopters and fixed wing planes regularly. Model aircraft have gone well in the US for the last 30ish years because people tend to self-regulate and the hobby hasn't been very big. Now that every Silicon Valley joker wants in on a perceived gold rush and DJI Phantoms work well and are available for a relatively low cost, hobby flying is moving into dangerous populated areas and the density of R/C craft is increasing.
I don't trust the FAA to correctly regulate these, and I see a very depressing day where I won't be able to fly as a hobbyist, but I also see an unregulated future where regulation-skirting companies (maybe they'll "crowdsource drone pilots" or something similarly "sharing economy"-esque) accidentally hit people with drones and basically say "so sorry, sucker!"
As for your latter point, that's basically what happens here, too. Lots of TV and commercials are filmed using drones, but the production company either sells the footage as "found footage" or rents out some non-drone piece of equipment (camera, memory card, etc.) from a drone owner at an exorbitant rate with the understanding that the rest covers the drone rental.
The FAA's roadmap here:
http://www.faa.gov/about/initiatives/uas/media/UAS_Roadmap_2...
indicates that they plan to implement these requirements for all drones which aren't sUAS with a line-of-sight requirement.
I believe these drones should be authorized for testing and commercial flight over unpopulated areas below 500ft and possibly above in certain airspace classes - basically, that the existing, frequently ignored hobbyist "recommendations" should be enforced as "rules" and applied commercially.
In the uk when doing commercial flying tests your meant to bring the aircraft you aim to fly along with you, what happens if you have loads of aircraft and are a seasoned hobbyist wanting to make money from your passion? You can get around it, do something for someone and just tell them to keep it hush and make a donation to you in some way.
