If your trying to build a site that will allow you to sell digital goods, you are going to have problems if you use a static site. With writefully the idea is you get real business objects you can build business intelligence into. So for example I only want users who buy a piece of content to be able to view it, I can do that with associations or some sort of logic to detect who bought what. It's difficult to do that sort of thing with static sites.
