First and foremost, to encourage the creation of "intellectual property".
But you did not argue in that way. Your argument seemed to be a rights based argument since you said that the important thing was that the author was compensated. If you wanted to stimulate creation then you have not shown that photocopying of books you borrow does not have a net positive effect on creation compared to not photocopying and mutatis mutandis.
