No argument there. It depends greatly on what the normal level of humidity is in any particular environment. In my environment at home if you dry your razor properly after use and store it outside the bathroom it would take a very, very long time for the edge to degrade to a noticeable degree. Other home environments in other parts of the world the degradation could be/is much quicker. It's probably more of an issue in long term storage and you have to take the appropriate precautions.
