A reductionist operating system theory? Have you ever heard of emergent properties? A system comprised of pieces can as a whole exibit other characteristics than the basic elements would provide. I think it is wrong to use the same small things for big things. You would not tow a tanker with your bicycle. Similarly you could use small pages for text files but huge page sizes when you need to transfer gigabytes or terabytes of memory. Its wrong to dictate ones size fits all.
