Nooo... I don't want something to exist that can absolutely prove that a photo is real. This only serves to enforce social norms more rigidly. These include reasonable norms like against committing crimes or behaving abusingly but it also includes stupid norms like behaving uncool or doing something embarrasing. The problem is, where do you draw the line? I think if somebody does something stupid or even morally dubious there should always be a way of forgetting it.

That you can't believe everything you see in the age of AI is a feature, not a bug. We are so used to photographs being hard facts that we'll have to go through a hard transition, but we'll be fine afterwards, just as we were before the invention of photography. Our norms will adapt. And photographs will become mere heresay and illustration, but that's OK.

I think here the same dynamic is at play as with music/videos and DRM. Our society is so used to doing it the old way - selling physical records - that when new technology comes along, which allows free copying, we can't go where the technology leads us (because we don't know how to feed the artists, and because the record industry has too much power), so we invent a mechanism to turn back the wheel and make music into a scarce good again. Similar here: we can't ban Photoshop and AI, but we invent a technology to try to turn back time and make photos "evidence" again.
