You made your decision from a place of power, which is obviously a positive thing. You have also commented that for you the money was irrelevant.
For Mustang, it's the opposite. He has said that the money is the motivation. He's said he needs the money to pay off a ticket. In my opinion, this is not coming from a place of power.
When considering whether or not to do something that may have negative consequences at some point, one needs to come from a place of power. Therefore, if something negative does happen down the line as a result of the pictures, at least the person can say, "Well, I enjoyed what I did." That's far better than thinking, "Too bad I did that only because I needed the money to pay off a ticket."
I suppose the point I'm trying to make is that Mustang's beautiful body should be celebrated for itself, not as a means of paying off a small ticket. It's his choice, of course. These are just my thoughts.
