Structuring has nothing to do with wax retention. A structure is a pattern etched into the base of the board designed to break up suction forces applied to the board as you melt snow sliding down the mountain. The difference between a structured and unstructured base is most dramatic in wet, warm snow, but the right structure for a given condition will always help.
Most snowboards come without any structure whatsoever, so even a brand new deck can benefit from a stone grind. More detail here
