Even if copy-writing, editing, marketing, cover design, and all of the like can be done by freelancers, most writers don't want to spend their time organizing all of those people, paying them, dealing with the taxes, etc. Some of the best people in those fields are staff at the publishers, and aren't even available for freelancing, nor do they want to freelance.
