I went back and edited my comment before seeing your reply. I originally interpreted “that no one ever saw” in Eliezer’s question “would I value art that no one ever saw?” as meaning no one else (besides Eliezer and, presumably, the artist who made the work).
I see now that maybe he meant “art that no human being has ever seen at all.” Which resolves the conflict, but seems like an implicitly contradictory supposition.
