you're saying copying a book is worse than robbing a farmer of his food and/or livelihood, which cannot be replaced to duplicated. Meanwhile, someone who copies a book does not deprive the author of selling the book again (or a tasty proceedings from harvest).
I can't say I agree, for obvious reasons.
Just as the farmer obtains his livelihood from the investment-of-energy-to-raise-crops-to-energy cycle the author has his livelihood by the investment-of-energy-to-finding-a-useful-work-to-energy cycle.
So he is in fact robbed in a very similar way.
You'd have to steal the author's ownership of the intellectual property in order for the comparison to be valid, just as you stole ownership of his crop.
Separately, there is a reason why theft and copyright infringement are two distinct concepts in law.
Big if. Practically, the movie studios aren’t poor because their product has instances of infringement.
So the median person who is harmed when something competes with his book authorship is someone making 20k p.a., not someone who is a major shareholder of a big firm.
