I think it is entirely reasonable to totally ban any media that has any person who haven't given explicit release on their likeness. It isn't too much to ask for valuing everyone's privacy.
That wouldn't have knock on effects like utterly destroying investigative journalism or anything.... There are tons of things that people would censor if the above were law that are not in the public interest to be censored.
In the US, there is no general expectation of privacy in a public place.
Implementing your proposal is also unreasonable: before one took a photo of their spouse in the park, they would have to clear the background of all persons or get their explicit consent.
