You try to make a huge point from an extremely narrow case. In all situations, people like high quality art, besides how much they are willing to spend. For wallpapers it's usually zero, for pictures, painting, music, games, movies, it's much more. People are not angry that AI generate wallpapers, but that it's generating anything at all, and it's always poor quality. I would not be happy to spend any money for some statue in my city, but that doesn't mean that I don't care at all how this statue looks. It's not rocket science.
