Utility is nonsense. It does nothing to help you understand and actively hurts you by masking the things you don't understand.

And I do believe that people can profit from trade. I do not believe that people must always profit from every trade. That there can be trades that benefit only one side, but that will still happen frequently because of the nature of people.

And the QVC example, all I see is a channel that hits every single sales-trick in the book and manages to sell overpriced crap to people who won't use it for profit year over year.
