Because the theory doesn't line up with what people actually do in real games. You have all of these metafaggots who tell you that water is S tier and you shouldn't use anything else, but that's such a boring playstyle, which you can see because the vast majority of people are using different beverage weapons. Stuff like Cola Cola's speed boost and alcohol's pain dulling effect can win games, but waterfags are terrified of downsides, so these options are "bad for you".
