I'll agree it only takes 'x' amount of hp to maintain a given speed on a level road but a taller gear (if taken too far) will make the engine 'think' it's working harder and will require greater throttle for the given speed.
Sometimes I think you have to give the engineers credit for for picking the correct gearing, although I can see a case for going lower for off-road use.
