I see your point, but I've never really given too much energy to considering whether what I do as a photographer really matters in the scheme of things. I do most of the things because it's what I love to do.
I do find it odd that a person's photo is the only thing that was taken. Makes absolutely no sense to me...

... and everybody always whined and complained, but guess who they sought out after an event was over and they wanted pictures?
