If you don't find value in the precise use of words to convey very specific ideas then yea it probably seems like nonsense to you. I assure you it's not, thinking clearly, and accurately conveying those ideas requires precise use of words or the ideas cannot be shared. It is quite constructive to draw such distinctions and agree on the definition of words before accurate communication is even possible.
I am pretty sure that, subjectively and objectively, this sort of nonsense discussion of the definitions of words and reality is non-constructive.
