Fahrenheit 451… Book burning as done by lawyers
For Bradbury’s book, this means that the reading public, the braille printer, the budding playwright, the school library face either higher prices, or legal restrictions on reuse or both. And they get no benefit from it. Clearly, the incentive of 28 + 28 years was enough to encourage him to write the book and the publisher to publish it. The evidence is that.. it happened. Retrospectively extending copyright is deadweight social loss — harm without benefit. But at least the book is available.
