The author's website sets a root font size of 18px. That completely eliminates any benefit you may have by using rems "for accessibility". Setting the root font size with an absolute unit completely overwrites the users' font size settings. Even the ones that the author mentions in the "The Real-real Problem" section. If you really want to change the root font size, you probably should use the `em` unit. It will be based on the users' settings.
