Define "silly." Is that like picking up pennies in front of a steamroller?
I like efficiency. Sometimes that's time efficiency, sometimes ingredient efficiency, sometimes fiscal efficiency.
I hate waste, but there's a point where avoiding waste becomes time-costly--and thus the efficiency of conservation of ingredients or materials conflicts with the efficiency of doing things as time-efficiently as possible.
So what is "silly" probably has to do with what one's goals are, and which goals are more important at which point. Everyone has their own goals, and nobody is wrong for having them, whatever they are.

When I started brewing I was much more concerned with fiscal efficiency, i.e., saving money; as my goals changed, fiscal efficiency became less important and the quality of the beer became more important. Also, time efficiency started overriding fiscal efficiency; that's one reason I bought a Jaded Hydra chiller, which changed a 15-minute-plus chilling time to 4 minutes.
Sometimes I go backwards in efficiency, in favor of the beer. I'm doing LODO techniques, and a copper Jaded Hydra isn't what I need to keep copper out of the wort. So I now have a stainless counterflow chiller, which is not anywhere near as fast. The trade is time for no copper. <sigh>
Fifteen years ago, with kids still at home, fiscal efficiency would have trumped all; now that I'm an empty-nester, that's less a focus.
