One of the final steps in preparing your work to be published is having it copy edited, which is to say that there are other steps. For example, your work needs to be revised. It needs to be read by beta readers, preferably ones who read critically. It needs to be read by an editor who will provide structural feedback.* It will then need to be revised according to the feedback and reception received. Then and only then is it ready to be hacked to pieces by the copy editor.
