Well, that's also a good point, since rendering takes hours if you don't have the best equipment. What perhaps we wanted to say, which you also seem to agree with, is that it is less likely for animators to recycle 3D animations than to recycle hand-drawn ones for reasons that changing camera angles and pressing "render" is easier than having to draw the mech again, frame by frame, doing essentially the same thing. I do get why you suddenly call me an optimist, that statement I made was rashly written.
Peace
