To take my own field as an example, as one author remarked, "software is a service industry under the persistent delusion that it is a manufacturing industry." In truth, most software has always been paid for by people who had reason other than projected sale of licenses to want it to exist, but this was obscured for a couple of decades by shrinkwrap software, shipped on floppy disks or CDs, being the only part of the industry visible to the typical nonspecialist. But the age of shrinkwrap software is passing - outside entertainment, how often does the typical customer buy a program these days? - yet the industry is doing fine. We just don't need copyright law the way we thought we did.
