Aperture is like iTunes. You don't even think about Finder when you use them. The location of files is irrelevant to the user. You just concentrate on the task at hand. It's sorta like iPhone/Touch/iPad apps: there is no file system that the end-user deals with. In fact there was an interesting article recently about just that: Apple more-or-less dealing away with the file system (for end-users) on iPhones and iPads. Really, they've already done that with iTunes and Aperture.
