I would also push back against the whole "this is just being perceived in public" thing, because you're not consenting to being perceived by the entire planet, you were consenting to being perceived by the people present and in the community. Like if there's a bully in the community, the community can do something about it or you can at least avoid them. Like you are consenting to interacting with a culture of like-minded people, and you know they're like-minded because they all showed up to the same event to do the same thing. That is not true of the open internet.
I feel this has some parallels to concerns over house/porch cameras which are proliferating these days.
I have no problem with the idea that everyone on the street is recording from their porch... as long as it's for their own siloed use, and it takes a conscious act for them to share it. If someone wants to stalk you, they'd need conscious assistance from your neighbors. If the police are tracking a hit-and-run, they need to ask people for footage during a time period, etc.
But the moment someone says "hey let's network all those with object/face recognition so that you can easily trace every person walking down the street", then we've got a problem.
I agree that we need a renewed social agreement on "no perception of privacy in public" concept now that cameras are everywhere, are smaller than a pinhead, and cost pennies .
Laws aren't sacred, they are just the rule over the living by the dead. All of our privacy laws were made when the technology , culture and demographics were completely different.
