Fowler's book is about simplifying mainentance and testability, not (necessarily) simplifying the actual code. He doesn't even claim his techniques are the best way to start programs, hence the "Refactoring to" portion of the title. Also, it's specifically about object oriented design patterns so the examples aren't intended to apply to other paradigms.
