You shouldn't expect privacy in public spaces. That's the nature of public spaces. In the US, freedom of press means anywhere public means you have no expectation of privacy, and should comport yourself as such; don't do anything or wear anything in public you wouldn't want to be recorded.

This is why paparazzi exist and how they operate. It's the dirty, dingy cost of having a free press, freedom of travel, freedom to hold public officials accountable, subject to the same laws you are; you can't waffle or restrict or grant exceptions, because those inevitably, invariably get abused by those in power.
