Photographers have a great deal of creative control. Put the same camera in your hands versus a professional and you will get different results even with the same subject. You taking a snapshot in the woods are not Ansel Adams, nor are you taking a selfie Annie Leibovitz. The skill and artistic intent of the human being using the tool matters.
Meanwhile with AI, given the same model and inputs - including a prompt which may include the names of specific artists "in the style of x" - one can reproduce mathematically equivalent results, regardless of the person using it. If one can perfectly replicate the work by simply replicating the tools, then the human using the tool adds nothing of unique personal value to the end result. Even if one were to concede that AI generated content were art, it still wouldn't be the art of the user, it would be the art of the model.
