Maybe for a certain kind of game. Survival horror, absolutely - as an aside, i really want to find a good survival horror fantasy RPG, I think that'd be really fun. But for mainstream fantasy games? It doesn't have the same weight or drama. The question isn't "Will I have enough supplies for this adventure, and if not how I can I make do?", but "Will the entirety my 100g worth of arrows in extradimensional storage last until I retire this character, can I spend less?"
