It's not so much that folders are counter-intuitive. The problem with them is that they impose a single, arbitrary structure on files that could be organized in many different ways. For example, you could have folders like AllMyImages/ or AllMyCatImages/ or CatImagesJuly2012/ but there's no way to anticipate what will be the most useful directory structure for all future situations. It would be more flexible and useful to have indexes over the files that let you dynamically organize your content according to attributes such as contains-cats, date, is-image, author, etc.
