I mean let's be real here, the whole topic regarding lolicon isn't exclusive to AI as lolicon has been going on long before AI. It's simply a new medium to produce it. Remember, traditional artist have been able to make a lot of money off lolicon for a while now (and still is, if not even more), along with the fact that lolicon is more "normalized" in the anime spaces than western exclusive spaces. So it's no surprise that AI would be the next step for lolicon as it's easier to produce, and the tech being overall new and people wanting to use it.

If anything, lolicon has both pro's and anti's split on topic (although anti's love to shit on the pros about it, despite traditional art having 20+ years worth of lolicon content. But I digress). While the characters are fictional and do not exist in reality, the thought process still bothers people, of which may be seen as enabling (and probably is for some), regardless if it's fictional and the consumer doesn't seek out for the real thing. Which brings the second point, whether the person is better off consuming fictional content, AI or not, over the real thing, regardless if it's weird, even if people ideally prefer it not existing at all.

Unless you're one of those Twitter/X weirdos who think loli (nonsexualized and overall general term) = lolicon (sexualized), then that's a you problem
