I was really thinking of imposing a framework where people know someones preference even when looking at the videos later. I would be fine even if there is no fine, if someone found me on one of your photos and say - look a lanyard, what a jerk for putting that online, without any additional consequence. EU came into my mind because of the existing GDPR and as a platform where this could be propagated.
No I would generally not want anyone to go to jail even it the footage wracks my life somehow, but I would want a mechanism to broadcast my preference to the recording world.
I think this is a key difference between US and Europe.
It seems like you believe that if the government passed a law then it will have meaning in society? It's still as meaningless as if you just wore one today.
