The evidence for the file system problem can be found in pretty much any book about user interfaces, but I have already linked to one in the post you are replying to. But aside from any arbitrary book on the subject, the evidence is not hard to find. All you really have to do is watch a computer novice try to use a computer for any length of time. I don't know what operating systems you are using, but My mac with the latest operating system still has a multiple "library" folders and a "system" folder. I presume windows 7 still has a windows folder, a program files folder, and documents and settings folders. Any unix type system has /usr /bin /var /etc . These things are so apparently ingrained it appears you are incapable of perceiving them. as for your third point, this is what is called the fallacy of the false dichotomy or false dilemma. The solution for this is that there's more than just the 2 options you are imagining.
