Yes, she can make a tshirt design on a computer and distribute it infinitely. But her fans are not going to wear digital designs; they are going to wear physical pieces of stitched cotton or polyester. I am aware of Cafe Press, but it is still not the same as distributing digital information at no cost. If I want a computer, it will have to be manufactured and physically delivered to me, even if all of the business is transacted on the Web. Maybe Cafe Press has an economic model that I don't understand, but it seems like somewhere, this will cost money.
