The smart thing to do is just to ban recreational use of these vehicles, but the reality is that many of the people who are going to become competent commercial operators are going to start out doing it recreationally.
I think it's a valued activity, but it needs to be coupled with the steps that could be taken to prudently mitigate reasonable risk, while recognizing that no activity is ever going to get down to zero risk.
The distinction between commercial and non-commercial or commercial and recreational right now is subject to a huge number of debates. If somebody pays you later for a photo that you took today, does that make your flight commercial?
We shouldn't be arguing over that. We should be focusing on mitigating the actual risk based on the activity, which has nothing to do with whether or not somebody is being paid.
