Have you read any Chinese poetry? AFAIK it inspired the "concrete" movement in western poetry. In just a few characters a Chinese poem can create a whole world. So while western poetry to me often just seems like word craft, Chinese poetry answers the "what's the point" question by creating a rich world in your mind with as few words as possible.
It demonstrates that with just a few subtle linguistic cues the human mind can be made to simulate an entire world. And, more importantly, if those cues are well chosen that world will be complete with memory, emotion, sound, light, and movement. Not because those things are in the poem itself, they exist in your response to the poem as the negative space is filled in by your imagination. In that way poets are engineers not of language but of the human mind.
