If the parents want they can restrict their usage. I prefer to monitor and teach my children how to use technology properly, and that also includes of course sex education because it's not by banning porn sites till they are 18+ that you solve the issue to me, but by educating.
Unfortunately we have among sex and other things still the mentality of 1900, except that today most 18 year old already lost their virginity, and he can't watch porn? Well...
Most parents do not have the technical skills to effectively limit that usage. The vast majority may not even be aware that software tools and features exist that could limit it. For that matter, I am aware, and the features on most products are insufficient... I shouldn't have to block Youtube at the router-level, but that's about the only thing I can do. Works for the Xbox, which is plugged into ethernet, but it won't work for the iPhone since it just does fallback to cell service. What's to stop the kid from buying some cheap Android device and swapping in their sim, so they can get around Apple's parental controls?
>except that today most 18 year old already lost their virginity, True when we were kids. But bizarrely less true today.

I think there are good arguments for claiming porn is more harmful than actual sex at that age, or at least some types or porn.
I agree that if the aim of the legislation was really to stop kids watching porn it would be better served by making it mandatory for ISPs to provide filtered connections for households with minors and filtered SIM cards for minors.
