I think you're missing the point, I wasn't talking about whether one should or shouldn't be a rational economic agent. Rather that an argument advanced based on rational economic thinking is invalid when talking about writers in the general sense as they do not produce their work based on the expectation of a reasonable profit. If Amazon keeps playing hardball with Hachette, they will drive down writers profits, but writers will keep writing books because they don't care about profit. eg. There will be no reduction in the supply of books.
