> An absolute privacy nightmare especially in places like Switzerland or Germany where recording people (subject focus) even in public is not permitted

That's the prime example of a law that can't be enforced and thus shouldn't exist. You go in town, you can be recorded inadvertantly, as long as it's not some creep stalking you, I say it's fine.

It can and is enforced. Again it's if the person is the focus of your video.

If you post a video online of someone's worst day which you decided to film for entertainment, they can legally go after you.
