I'm in favor of IP laws, including copyright, but with the idea of creating incentives for people to create. Putting Sherlock Holmes in the public domain is probably not going to have much effect on Arthur Conan-Doyle's writing output, though, so it's probably a good thing at this point.
>Putting Sherlock Holmes in the public domain is probably not going to have much effect on Arthur Conan-Doyle's writing output, though, so it's probably a good thing at this point. I'm playing devil's advocate a bit here, but couldn't the precedent have an effect on the creative output of people alive today, based on their desire for their descendants to inherit something valuable?
From an economic and psychological perspective though, it gets increasingly silly as copyright gets longer and longer. We know that people discount future income, and when you get to time frames of 70-90 years, the present value of any additional income is near-zero.
