This sounds like a regulation issue to me. If it's regulated it can't be inevitable that "most people" are breaking the law. And if there is a resistance among people then hopefully it will be regulated (I'm talking outside the US now, i.e. where there is a positive correlation between what people in general want and what laws eventually become).
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.
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.
