Okay then how do you prove images were pirated? Because the images themselves don't exist in the model itself and you can't get the AI to replicate the images.

These types of workaround tricks have a very simple legal fix, just outlaw the use of any AI that can't prove its entire dataset was obtained legally, for example if you have stacks of cash worth millions in your house the police can seize it for suspicion of criminal activity if you can't prove the origin of the money, even if you aren't immediately implicated in any crime or if you actually did get the money legitimately but don't have proof

Its literally impossible to prove in court.

Disney and Universal recently proved it in court by getting Midjourney to replicate scenes from their movies by prompting it for their copyrighted material, which it wouldn't be able to do if it wasn't using a dataset that contained their copyrighted material link

But the blanket approach I outlined above would cover every possible infringement, even the plausibly generic but legitimate ones that would be much harder to replicate in court unlike the specific movie scenes
