The difference there is the kids were just watching stuff. They didn't understand or seek out transgression for the thrill of it. here's perhaps a better parallel:
TL;DR on that is what can and can't be shown in Australia is anatomically tone-deaf so it's driving labiaplasty as women are getting the wrong impression of what's normal.
I could see the argument that if what you get out of porn is "being naughty" and "being naughty" used to be going to see "Deep Throat" at your bachelor party but is now swapping Vannable material on Discord then yeah, the extremity of porn could arguably be driving the consumption of child pornography. I'm not entirely comfortable going "it's driving people to break the law" because fuckin'hell I broke into a cold sweat the one time I got hits on a Traci Lords search but then, I consider myself to be a reasonably moral person and "I've been hiding my porn addiction from my wife" speaks to certain failures of character.
