I find it incredibly illuminating that upon asking me how we should go about doing the thing you challenged me to do, you engaged with none of it and instead descended even further into niche technology to try and make it seem like, because it's technically possible, we shouldn't even attempt to regulate it.

No, we can't stop people sharing it over encrypted channels. What we can do is mandate that these AI include identification data in their generated images, which is tied to a singular person. And from there, we can identify and prosecute the creator, and through court orders to whatever platform holder is at play, get a list of everyone who downloaded it and shared it.

We do this shit constantly for major rights holders. We know how. We just choose not to because too many people think it's "just boys being boys" and enable a culture that thinks sex offenses aren't worth our time.
