When generative AI can create such good fake images a valid c2pa linked to the source camera will become mandatory for an image to be considered authentic.
Edit: Thinking through this a bit more, I think the goal of _authenticating_ a photo using C2PA is still useful. If the goal is to remove them to get a "naked" image, that's fine, such an image is then inherently no more or less trustworthy than any other image. If the goal is to figure out how to reproduce a valid provenance chain on top of an altered image then I have problems with that.
