Firstly, thank you for posting this! I'm one of the people who primarily values the art on its own merits, and not on whether it was made by a human chiseling with rocks and ground up flower petals for ink, or an AI generating something. The primary part of that value assessment is definitely how it makes me feel. Your post is the first time I felt I may actually understand the other side.
Speaking only for myself, I can absolutely understand where you are coming from. It makes a lot of sense when put this way. But, I think the difference here is that what you are describing is deceit, and it's the deceit rather than the output, that would bother me in all of your scenarios.
For example, your strongest point in my opinion, is the AI girlfriend versus the real girlfriend. That's a phenomenal argument because it is in my opinion an accurate analogy so how's the logic side strong, and it's also a horrifying one, so it hits hard on the emotions as well as the logic side. The beauty of this is not lost on me, you have created amazing art with that argument! That's the kind of art that really resonates with me.
But zooming in on that scenario, I think the key is disclosure. If the person dating the AI girlfriend knows that it's an AI girlfriend, that doesn't float my boat but I know people who would actually prefer an AI girlfriend to a real one. Again, not for me, but I recognize that it is for some people.
Same with seeing a pretty picture on the screen. If it's being presented to me with deceit behind it, either a person claiming they snapped the photo or made the art digitally when it is actually just AI, then it does ruin the art for me. If it's disclosed though that it is made by AI, I can evaluate it on its merits. Just like in your table example above, I may appreciate the effort and personality behind a more flawed piece that was made by hand, but I also appreciate the precise lines and geometry of a machined output. The key is the honesty and disclosure behind who created it. I get a different value out of the handcrafted piece than I do the AI generated piece. One isn't necessarily better than the other, just different.
Where I do feel a little hesitant on the AI side, though is as you get at the capitalist destruction of art. Without a doubt, the middle level of artists will be hollowed out. I suspect there will always be a place for the traditional artist, but I do worry it will be diminished. On the flip side, I've been able to use AI to take photos of my pets or family, and reimagine them in interesting ways. I know it's not real, I know it's computer generated, and I'm not hanging those pictures on my wall. I simply do not get the same joy from seeing those pictures as I do the originals. I could be wrong here, but I feel like that is the heart of your point, and I think it's a good one.
