You aren't putting yourself in the shoes of a beginner. The real issue you and the author both run into is assuming that the wants, needs and learning styles of all people everywhere are identical. There's a good argument to be made for expanding the variety of styles and types of documentation available in order to cater to more ways of learning, but not a good argument to be made for suppressing or removing existing documentation since that boils down to "all right, let's cut off those people to focus on these people". One big example that's not covered, but relevant, is how many (free, so potentially competing with the author's book) workshops or online complete guides to learn Python or Python-related tools have been popping up the past couple of years. Having an experienced coach who walks you through everything your first couple of days and gets you acclimated is a huge deal for some people (while others prefer to read on their own in an undirected way), but isn't accounted for in the article.
