What if you could afford to buy one with a thermal imaging system for use to track wounded deer? Does that change anything? I sure as all get-out don't want to see one overhead when I'm getting ready to draw back on a nice deer, but if it helped you find that trophy you had trouble tracking...

My opinion on the whole matter is that you should only be able to fly them over property you own or have permission to walk on... public property is another matter I'm not going to think about.
