I know the purpose of your post is to make light of the article. However you are close to showing why Regions suk.
In the book analogy one thing is clear, you did not reorganize chapters the way that some bad programmers rearrange classes within regions.
Your comment is facetious when merely discussing books and chapters.

Imagine reading Harry Potter in some arbitrary order of chapters, first all indoor scenes then all outdoor scenes...(public/private)
