Gonna say the thing: IDGAF if kids see porn online. I'd far prefer children explore pornography and learn what they are and are not comfortable with; rather than risk being exploited by less-naive children or adults. Open access to porn is the harm reduction. They are images on a screen.

Let's not pretend that today's adults never saw porn growing up. I, a Gen Z kid, saw porn at young ages. There are reasons I am "off" in the head but none of them have to do with porn; and many of them have to do from forces who, among other things, push the purity culture narrative. This is the exact same over-dramatic messaging as the USA's War on Drugs or its "Satanic Panic"—both of which source from purity culture and both of which have harmed significantly more kids than what they hoped regulate.
