the business model of a merchant is to buy something cheap and sell it at a more expensive price. if this business model would be copyrightable than nobody else would be allowed (not until he/she licensed it) to buy something cheap and sell it at a more expensive price. the one merchant who invented this concept would then be the only merchant in the world, and as the other guy who invented "licensing" would probably not have "licensed" licensing to the merchant (as the merchant would then have a license on licensing and would have just licensed licensing to other people) the merchant would be forever the only merchant in the world. note: yeah i know this is absurd, but not as absurd as the notion, that business models are copyrightable. (or should not get copied because of .... whatever)
