Rick,
I think you and I agree totally. The book example, i.e., passing a book on to friends and relatives, is the same as sharing music with a small group. My family is always sharing books they've read. Last year I gave more than fifty books to my school's library with the idea that many others will have a chance to read them.
It's true that single copy of a book could be read by dozens of individuals--with only the one initial sale, and only the single royalty check going to the author. But it is clearly a different ball game when thousands or millions have immediate access to digital and near perfect copies.
