gives a random stranger the ability to identify you and perhaps even contact you? Could somebody doxx you in real-time? I don't think I would want that.
I'm going to put my McLuhan hat on and postulate that the age of the "stranger" may be going away.
When you think of it, humans evolved at a time when the only strangers were enemies. Governments and corporates can exploit that fear only so much before people start rejecting that model.
