The advice from Google is wrong. In any competitive market sooner or later you could feel the full force of negative seo. By establishing a disavow file you show google you are in control of your links. By including the scraper sites that have your content you can keep ahead of the competition and if a negative seo attack happens you are well placed to amend your constantly updated file.
The Disavow File should be the first thing you think of when it comes to seo. There is no point building Rome when someone is trying to kill it from the start.
