"In any case, I'm not saying utility can't exist. I'm saying some universal utility can't exist, or if you wish: sorry, guys, you can't determine my utility function for me. I'll do it myself, thank you very much." The article does not posit a "universal utility function", nor does it require determining anyone's individual utility function. It merely requires that utility functions exist and that a comparison of the resulting utility is meaningful. "If we could have a "formalized utility function" for "most reasonable cases" we'd hardly have different morals, political parties, and so on..." Only if you have a universal utility function. Which you are the only one proposing.
