It shouldn't, you wouldn't be able to photograph candid moments in public of your own family/group of friends if anyone's else face showed up in the picture, that's not a world I want to live in.

It would also completely kill any form of street photography, even if you don't appreciate the art it would kill documenting times and places for posterity, for what benefit exactly?

Laws have non-binary options - for example, most countries have laws controlling industrial-scale air pollution which do not prevent you from grilling at home.

In this case, I think it would be interesting to think about the most concerning area: linking a person in a photo to their real-world identity. It seems like there could be restrictions on how face-recognition databases are built and accessed, possibly incorporating intent to harass or intimidate as an aggravating factor, and possibly linking across time and place. If I take a picture of some guys playing basketball or chess as I walk around town, I don’t need to identify them in my art exhibit entry and I certainly don’t need to link one of them to a different time and place without their permission.

Strengthening of your right to privacy against an entirely new paradigm of state and individual surveillance. It is a new world.

I actually don't find it hard to sacrifice the recreational photography of strangers, but I do have a hard time balancing it with the need to photograph crime and government entities overstepping their authorities.

I don't have a good answer for it all.
