Notice, how loose is the relationship between the societal benefit and implementing author's will. Society's goal in by itself is not to make authors happy. The goal is for the society to benefit in a long term from all the innovations and the creativity. Authors' will enforcement process is secondary and is to serve that goal through created incentives. The enforcement process is also expensive and society needs to somehow balance the short term enforcement expenses versus the long term benefits. Which mean, that if society finds another, cheaper, way to bolster creativity and innovation, then copyright protections may get thrown out of the door.
