> someone else taking a photo of me doesn't harm me in any way With today's facial recognition technologies, if that photo has GPS coordinates and timestamp attached (most likely it has) it means now somewhere (most likely in several places - cloud, social networks, ad networks, etc.) it is registered that you were at that place at that moment. Not everyone is happy that their movements and whereabouts are being registered. Well, you can argue that we all carry a smartphone so anyhow our mobile operators (and so, the government (yours and maybe others too)) register our movements history, but at least you can choose not to carry a smartphone, but how can one choose not to be photographed/videotaped?
