Yes, even if we wanna consider the "how it's produced" (and here we could agree that the process is automatical and not an "artistic attempt") as did by Sidi Usama2, there is also another aspect, that of the final result we get in our hands. So, there isn't just the aspect of "creating an image" (about which I may even agree with Sidi Usama2), but there is also the aspect of the result of the print, which is an image, and so I can easily see the reasons of its prohibition. Different issue for digital photography, as you have mentioned.
