So 999 people that are just making an image need to be DRM'ed so that you might catch the 1 person making "realistic but deceptive" images... like this is some kind of special case of ... internet images.
This isn't DRM right? This is metadata attached to the image that makes it clear it was synthetically generated. The public has a huge incentive to know when images are AI generated and the harm to legitimate users seems pretty small: aka someone might complain online that you use AI
There's a world where all the big platforms automatically flag AI images thanks to SnythID and other techniques. The more ubiquitous it is the easier it will be for them to make that a reality.
And given that governments, large corporations and well funded bad actors will be able to generate non-water marked images this will legitimize AI generated propaganda and scam images as truth. I wouldn't be surprised if a forensic junk science grew up around it to further legitimize it as well.
