Interesting review - I’ll be sure to get the book. I have to disagree with one part of the argument though: the marginal cost of reproducing an information good is never zero. The problem with the argument is that it imagines an infinite number of copies. But that’s daft. In the real world, there will never be an infinite number of copies, because we have no use for an infinite number of copies. Even if every person on the planet wants a copy of Cory’s latest, that’s still only a few billion. So the marginal cost might be small, but it’s not zero. And if it’s not zero, we still have to figure out how that cost is borne. Someone’s labour still matters.
