In the united states the first amendment of the constitution makes it so that any public usage of camera tech cannot be controlled by the state. Except in some very specific scenarios.
I'm repeating a comment of mine from another thread, but this is not true. Both recording the audio of a conversation that you aren't party to and deriving biometrics from video without consent are both broad categories that are regulated depending on the state you're doing the "public usage" in.
If it was also illegal to (for example) input a photo of someone non-consenting into any kind of AI model or post it to any other online service? Then I don't see much problem.
