By that same logic, should consuming lots and lots of protein yield bigger, stronger muscles? Or perhaps in both cases, the body must experience stimulus such that the tissues "know" they need to get at the necessary supplies coming in. Why build muscles, or stronger bones, if the body overall never does anything to need them? It would be wasted motion from their point of view.
