To be fairer, poetry like many other arts is highly subjective. The difference between a good poem and a bad one may have more to do with comparisons between other works at a given point in time than it does with any sort of "ideal poem".
Same thing going on with dalle-2. Hell, even formal mathematics has trouble justifying "why" a particular problem is worth solving.
I think people take into account the author, their sincerity, their experience, and how those words personally make the reader feel. This is the same reason I love Radiohead but would probably hate a Radiohead knockoff made by some AI. It's more about the people in the band and whether or not I relate with their message than it is about whether or not they are objectively good to listen to (they aren't, many people hate that band).
Being highly subjective doesn't make its study less worthwhile in the slightest and study of subjective topics can still possess rigour and commonly held opinions derived from first principles (i.e. "taste"). Look no further than the study of art, music and literature and philosophy to see just how much humans enjoy deep dives into arbitrary rules. It's maybe even part of what makes us human.
