Actually, i cant comprehen the exact meaning of your passage. I think you are arguing about whether grammar or vocabulary is more important. In my opinion, both are important.

as you can see. Vocabulary is good. You can speak so many words and express your feelings through many ways. But all of that will become useless with no grammar or you can say a way to arrange your words and even meanless. In addition, you need a right (not literally right ) sentence to fully give meanings, especially in writing. people will read your sentence and imagine the situation in that sentence. If the grammar of the sentence is wrong, It will makes people misunderstand or even meanless.
