some people might argue that these are not all advantages -- at least not universal advantages.
there are those who see square taper as a better solution than "modern" press-fit BBs. (personally i have not had issues with high-end bikes and PF/BB30, but that is not universal.)
wide rims and tires are less aerodynamic at low/no yaw. (even when wheels are designed for wider tires, they still take an aero hit.)
rim wear... really? i can think of many perks of disc brakes (and i own many disc brake-equipped bikes!), but not many people are retiring wheels these days due to worn out brake tracks.
i take your points -- just saying even in the examples you provided not everyone sees it the same way.
