Outcomes not being well defined != unnecessary or worth getting rid of.
You seem to confuse physical existence and idea. Presumably a physical object can be painted but ideas can't. Lot's of things exist that can't be verified by sight, touch, etc. In my opinion being a good teacher is not something that can be reasonably measured. I'm open to the possibility that I'm wrong but have seen no evidence that I am.
