...except that a book is an original work - your genome is derivative of your parents, and very similar to your relatives, and still somewhat similar to people of your ancestry.
I get the argument that it is a derivative work, but a personal genome also has the unique property of literally being the absolute essence of my own person. I morally and ethically possess a right to the usage of that essence, and I think it would be a very good idea for society to set up a legal framework that protects that right.
