Agreed. This product seems pointless because nobody's interested in a proof of authenticity (except maybe in certain legal niches?)
I take pics for me and my friends and family, and AI has almost zero impact on this (although, face swaping is lots of fun, and everyone understands it's fake and a joke).
Edit: also, and more importantly, the question of authenticity is moot. The point of art in general is to say something / make a statement, and certainly not to produce a faithful representation of the world. Anything that's not an exact copy (which is hard to do if you're not God), has a point of view, which gives it value.
Taking pics and videos of events with political ramifications and being able to show that it isn't AI generated or tampered with has HUGE utility, not the least of which by reporters and restablishing trust with disaffected.
The idea isn't a bad one in some cases like travel photography. Between background people removal and lightroom a good chunk of travel pictures are not a good representation of what you can expect. on Instagram there are plenty of pictures of people standing alone in front of the Eifel tower or at inari gates in afternoon lighting that is unrealistic outside the pandemic or a 6am shot. Or take cherry blossom viewing in tokyo. More trees are white or very light pink but you would not know that looking at what people post often the camera auto balancing to make them more pink because if it doesn't people think there is a problem with the camera; that incentivizes sony, canon etc to build that in.
