Hunting is actually taking resources from someone's property. A drone flying over your property doesn't harm you at all. Airplanes don't have to get permission from me to fly overhead. They can even legally take photos of my property if they want.
Just the other day some recreational pilot crashed in a field near me, and he didn't have to have a flight plan or anything. You don't even need a pilots license if it's something like an ultralight. Drones are vastly safety than that.
