It's simple, you don't write a paper for the sake of writing a paper. You write a paper for others to believe your argument. If you don't think from the reader's point of view and only focus on your own long speech, this kind of paper will be boring for readers to read, and it is a problem whether they can finish it, let alone convince your argument. So we must think from the reader's point of view, what are the highlights of this paper, and where can we attract readers to continue reading. If you don't consider it from the perspective of the current readers, it is just like cooking without considering what diners like to eat, which is divorced from reality. A theory divorced from reality is meaningless!
