I don't know man, I probably wouldn't even want forks (picking something of "obvious" utility) in my house if I were the ONLY one in the world who knew about them. What would guests think? That I'm some kind of weird food-impaler, maybe a closet Sadist. If people didn't use forks, choosing to have forks wouldn't be a foregone conclusion at all. Even all by myself.

You entirely undervalue the social context of objects, including objets d'art.
