I see your point, but I think that this ignores that people make emotional decisions about money and buying things. Maybe that's not you, but I think any marketer or economist would agree with that statement. The things we buy are inherently irrational and based on feelings, not features. So a world that is purely driven by facts and figures and not feelings is a sort of "what if" scenario and not something that will ever actually happen (as long as humans continue to be human).
