I think the article could easily be rewritten from the perspective of "dumping your excess thoughts / stream of consciousness into note files for later examination or future discarding is good because..." Because as mentioned, some notes are evolving documents, and others are just scrap files. And I do get a lot of value out of shelving thoughts and ideas for many of the reasons the article describes. It's just written as an unnecessarily grand sweeping generalization.
