Alternatively. Author X spends maybe a year of his/her life writing a book. They sacrifice their free time to produce this book. Obviously, they aren't doing it for the love of writing, they are doing it to earn some money from it. Now, if everyone in the world downloads that book without paying for it, then that author gets nothing. But, hey, it's okay to download the book because the author can afford it. Suddenly, because it's alright for one author, then it's alright for all authors. Suddenly, you get no to the point where people stop producing books because no one pays for them anymore.
