You don't need to be agile if you know what you are going to create and have it worked out all the way up front. In a perfect world, you would only have one iteration and that would be it. Users doesn't need to be external users. But the main point of the Agile manifesto is to get started - and adjust as you go. It doesn't hurt to have a plan up front, but as long as you have a rough idea of where you are going, that's often good enough to get started.
