You're taking a global view of a very narrow position, and ignoring enforcement. I can take a photo of you every time you leave your house, or drive in your car, and there's absolutely nothing you can do about it. The government would have to overcome monumental constitutional issues to prevent me from taking your photo in public. On top of that, how do you enforce such a measure? I think as a thought experiment, tell us where you live and maybe someone will come and take a photo of you every day, and you try and stop them. Heck they might already be doing that now....
