Because buffers are associated with file names and not files.  Changing
the buffer name would break backup for instance, which (by default)
renames the file and then writes it again.

I don't think there can be multiple buffers visiting the same file, thuogh.

Something like this:

(defun rename-this-file (new-name)
  "Rename this buffer's file to NEW-NAME."
  (interactive
   (let ((file (or buffer-file-name (error "Not a file"))))
     (list (read-file-name
	    "New name: " (file-name-directory file) nil nil
            (file-name-nondirectory file)))))
  (if (vc-backend buffer-file-name)
      (vc-rename-file buffer-file-name new-name))
    (rename-file buffer-file-name new-name)
    (set-visited-file-name new-name t t))
