I do take exception to this part though: "A hobbyist taking a picture with a UAS presents no more of a risk than a professional photographer doing the same."
I think that unlikely. A hobbyist with a POS $500 UAS is going to fly differently than a professional photographer with a $5000 UAS carrying a $3000 camera and a $1500 lens. When a large portion of your business's infrastructure is on the line, you tend to be a little more careful.
