The only solution to your concerns are legislation, and that is not going to happen in America as everyone has a video camera in their pocket and the 1st amendment exists. Private establishments are free to make rules regarding the use of these on their grounds assuming that the user is not using them for a disability related service.
I'm aware of that of course. No one can turn the tide against the market. But why do they bother, then, with the whole show of making it only record with a light? You agree that that's just theatre to seem less invasive than they inevitably will be?
I'm not based in the US so hopefully some local laws will help me out a bit, but at the end of the day, the law is not my moral barometer. I will respect the rights of the users of these devices while also exercising my own rights, as much as I am able to, to treat them as social pariahs.
