I doubt this would do much to stop kids from looking at porn. It would only intimidate people that are afraid of breaking the rules, not people that just want to find what they're looking for. By this logic kids can't buy alcohol either.
2/5s of Gen Z can't even navigate between folders on a computer, according to studies, with CS instructors saying they need to introduce directories as a concept. Yes, it will.
2/5ths of Gen Z not currently knowing how to navigate between folders in a hierarchical file system doesn't mean that 2/5ths of Gen Z is incapable of learning how to navigate between folders in a hierarchical file system.
The gap between present knowledge and capacity doesn't exist due to incompetence, it exists due to lack of motivation, and rest assured, once teenage boys discover how great boobs are, they'll have all the motivation they need to learn how to use technology to achieve the goal of viewing and appreciating that kind of material, pretty much regardless of how many restrictions you put in their way.
They'll make their own in a paint app or with ASCII art in a notepad, push come to shove, but that won't be necessary. It's hilarious to think that states have the slighest hope of winning the whack-a-mole game of trying to sue every single website on the entire internet that hosts any pornographic content.
How many people do you know whose first introduction to porn was "that's sounds cool, let me look that up?" Versus discovering it by accident, exactly what a law would effectively prevent?
But again, none of that will be necessary. Rule34 websites, imageboards, video game rendering glitches... the list goes on and on.
It's truly delusional to believe that it's possible to exhaustively censor imagery of the human body from the most motivated seeking/viewing demographic on the planet.
Are you by chance a woman? Were you homeschooled? Do you not have memories of being a teenage guy in the US public school system? I don't mean to denigrate you, I just cannot fathom how anyone can possibly credibly believe that it's even slightly realistic to keep teenage boys completely unaware of what boobs look like in the real world.
Oh, man. You just reminded me of teenage me trying to make something out in scrambled porn on cable TV after midnight. You could kind of see the thrusting, but it was barely stimulating. Those were tough times, let me tell you.
I was literally looking up Zero Suit Samus fan art on my Wii's web browser when parents put parental control software on the computer.
When I was grounded from all computer usage, I'd pull up Catie Minx photoshoots on a first-generation Kindle, with the e-ink display that had image update latency measured in seconds.
All of my friends would go to these extents and more to access this kind of material. I was introduced to dumpster diving by a friend for this reason. I had another friend who got caught for shoplifting adult magazines from a bookstore.
I don't think the motivation and ingenuity in seeking adult content is generationally restricted or particularly unique at all, it seems to be true for every guy I know, including those who were born in the 50s, 60s, 70's, 80s, 90s.
I genuinely cannot comprehend the thought process of people who truly believe that a few targeted lawsuits at major porn sites is going to make a dent in what might be one of the strongest behavioral drives hardcoded into the human genome.
I'll also add that regardless of any access to web or printed materials, boys will get interested in boobs and seeing more of them by seeing them in the real world, on real women.
There is like no stronger instinct in human DNA than for males to be attracted to females. If it weren't that way our species probably wouldn't have survived down the millenia.
I'm not opposed to measures that try to make it harder for kids to get at porn. But it's going to be pretty much impossible to do that as long as we want adults to have unimpeded access to it, and we do.
One option would be to put the responsibility on the distributor, and not give them the option of a "you must be 18 to enter" fig leaf: if a kid is found in possession of porn that can be traced to your web site, you face serious fines and possible imprisonment. But that would basically eliminate porn sites for everyone, since it would be impossible to prevent it from finding its way to kids, and we can't have that.
Are they capable of using computers to achieve their goals? Yes. Does that require navigating folders? No.
EDIT0: I remember writing a 4 line program to crash the school computer (recursively executing itself) on notepad, and I'm pretty sure I didn't know what folders and directories were.
I can also attest to many of my coworkers not understanding what file extensions are, while being over 40 and working in aeronautics.
