"A true fan is defined as a fan that will buy anything you produce. These diehard fans will drive 200 miles to see you sing; they will buy the hardback and paperback and audible versions of your book; they will purchase your next figurine sight unseen; they will pay for the “best-of” DVD version of your free YouTube channel; they will come to your chef’s table once a month."

I think the point is, people are fans so they want to collect and have a pride of ownership.
