Not sure I fully understand your meaning. I'm not critiquing the use of language for building up abstractions. It's useful for that. Just that removing any underlying reality leaves the abstractions hallucinogenic and meaningless. Language evolved to communicate "this plant with red berries kills you". That involves color, classifications, and an abstract understanding of death; but all of those are rooted somehow in physically shared reality which was perceptible before we formulated a way to communicate it. Taking that sentence and abstracting further from it without symbols remaining pointers fixed at the physical realities of red, plant, berries or death, you end up with a hall of mirrors. That's insanity.
