You seem to be implying that there's real waste to be cut and this is not necessarily a bad thing? If so, sure, but this is not the way to go about it.
It feels very much like a hindsight perspective. Sure, a lot (most?) scientific research will not be immediately beneficial to anyone. Some will never be beneficial. But you don't know that until you research it, that's why you're doing the research.
The only surefire way to prevent waste in research is to do no research at all.
