It seems to me that it’s an exceptional case that there’s some idea that’s would benefit society but is only economically viable under the current copyright regime. But our laws apply protections that are only needed in this rare instance to all ideas. I highly recommend “Against Intellectual Monopoly” by Michele Boldrin and David K. Levine. It changed how I view IP a great deal, and the final chapters are dedicated to how we could practically transition away from our current system.
I’m not an anarchist. I think the government has its place. But it’s undeniable that a lot of fundamental research is held hostage by politics: Certain ideas are in vogue and get funded, while the new ideas and those pursuing them must wait, or perhaps never get funded for whatever political reason.
The profit motive enables risk takers to get funded with high risk, high reward ideas. If there was no way to capture that profit, we would be subject to political whims for the most important innovations for society.
I’d be curious how many actual world-changing innovations were ONLY pursued because of the existence of copyright, that don’t belong to a class of innovation (like pharmaceuticals) that could have a solution, whether copyright, subsidies, or something else applied to the industry as a whole. I don’t doubt that there are some, but I would be shocked if their benefit isn’t dwarfed by the innovation lost to the anticompetitive nature of patents and copyright.
I'm fine with initial research being funded by the government, and entrepreneurs attempting to take that research to commercialize it.
That is the clear-cut case for intellectual property, but it’s the same principle for books. I’m not going to write a book that takes tons of effort and exposes my hard-won knowledge if I can’t profit from it, despite how easy it is to copy text. Food for thought
