I disagree. If it's impossible to tell the difference, people WILL start distributing collections of real and artificial child pornography combined while labeling it as 100% artificial. Most public websites will make both against the terms of service, but it makes it much harder for victims to get support from law enforcement to take down genuine CSAM.
Also, now that it's legal to own and consume content featuring realistic depictions of sexualized children, do you think that will lead to fewer or more children getting abused?
