This isn't a privacy argument, you already (should) have privacy in the situations where you're not around other people or out in the open.

This is about the times when you're out on the street with everybody else. That's when you can't reasonably expect EVERYONE TO LOOK AWAY when you walk into a store, or buy a coffee or throw your trash on the ground.

It's those times when you're not private. You know, in public.

These things aren't legally protected because our cultural and instinctive expectations forbid them. Try walking down the street and looking every single person you pass directly in the eye for as long as they're visible. See how they react. Follow them around. Write down everything they're doing. Let us all know what happens.
