From what I remember of those shows, even though it was broadly a harem anime, they at least had the taste to not sexualize Sasami, right?
Tenchi Muyo? It remember it being pretty tame, particularly compared to later raunchier harem anime like Love Hina. I have no idea how the more recent series went, though.
Also, IIRC the Jurai girls (Ayeka and Sasami) were listed as "over 700 years old", but it was a technicality because they spent 700 years in suspended animation on their way to Earth and everybody just treated them their age. I don't think they really count (plus Ayeka was... something between 17 and 21 depending on where you looked).
I can see the logic in the idea, but it's sort of a fallacy that someone who gets off to child porn will find cartoons of child porn an acceptable substitute. For this idea to work, the animated fake CP would have to be effectively indiscernible from the real stuff, and we're definitely not there technology-wise yet - and even if we were, I'd imagine CP traders would still have databases of which vids and pictures are the "real stuff" and value that media even more…
That's the big problem with that solution, yeah. Let's use a less taboo form of entertainment as an example here...
Consider horror movie fans. Some of these people are in for the scares, others are fascinated by the gore, and a few are a bit of both. But it's all fictional, all staged, and increasingly these days all CGI. But while horror movies are readily available and not really regulated anywhere in the developed world outside of recommended age ratings, there's still a thriving market for
the real stuff. Snuff movies, suicide footage, graphic car accident videos, war footage of people getting their guts ripped open by machinegun fire, that sort of shit. Now, not every horror fan is going to be into real life gore, far from it. But the real life goremonglers, although likely also interested in horror movies, aren't going to be satisfied just watching someone's face being peeled off in CGI when they know they could see the real thing in a Mexican cartel execution video.
Same deal with pedophiles. Not every lolicon is a pedo. But every pedo is
very likely a lolicon, and you could pump their eyeballs so full of hentai it gushes out of their ears if you wanted to, but it would still not be enough. Given the chance, they'd still go looking for the real stuff because
that's how they get their kicks. Just like with snuff fans, it's an innate attraction that can't fully be sated by a "fake" version of what they
really want.
They're fucking mentally sick. If these guys are looking to avoid problems, they're free to look for therapy, but
they need to stay the hell away from children. For their own good. All it takes is a quick lapse in willpower while alone with a kid, and these guys start diddling.
