> The morality ascribed to old business models probably won't disappear until the people who grew up in earlier times die. (I am reminded of John Philip Sousa railing against sound recordings in a 1906 Congressional hearing).
To expand on the morality point here:
In most areas, we recognize that we need to be careful limiting innovation for the sake of existing markets. For example, we're not trying to ban electric vehicles just because it makes it harder for gas companies to make a profit. The existence of DVDs and CDs lessening profits of movie theaters and concert halls is not a good argument to make the technology illegal. We didn't ban typewriters because they put the illuminated manuscript writers out of business. We do regularly get the government to interfere in some cases where a regulation or restriction clearly helps the market, but we try to be kind of careful about how we do it, and we view it through that lens: as an artificial restriction that is justified because of its social benefit.
However, with copyright it's really difficult to make people even understand that the market and human rights are being restricted in the first place -- it has that moral quality for a lot of people. Part of it is the name: "copyright" implies a right, but it is not a natural right. There is no inherent property/personal right to an idea, there's no way to derive a natural property right that is a restriction over what other people are allowed to talk about or build. It is an extremely modern idea to believe that inventing an idea implies that you own the idea itself, or that inventing a story means that the story can't be morally retold without your permission. So copyright isn't a "right" in the traditional sense, it is a government restriction on an innovation (easy copying), that helps prevent that innovation from disrupting the existing market too much or putting people out of business.
That's not to say copyright is bad or that we should just drop it tomorrow, but we should be looking at it through this lens; copyright is a subversion of natural market forces and a restriction on the natural human right to communicate, copy, and build on information they see in the world. Copying is a fundamental part of culture and a fundamental part of what it means to be human.
As such, we should be highly skeptical of copyright expansion, and we should be constantly evaluating whether or not the market really needs copyright restrictions at their current level. We should be actively looking to evolve the market so we can weaken copyright, because copyright is an artificial restriction on natural human activity, and an artificial restriction on the free market itself.
When people talk about expanding copyright, the burden is on them to justify why it's worthwhile to restrict human rights. Just saying that some businesses will fail isn't good enough, copyright is an extreme measure we're collectively embracing so that we can prevent the collapse of the entire creative market. Unless we're talking on that scale, we probably should be weakening copyright over time, even if it means a few businesses fail or have to pivot. In general, it's OK for the market to evolve and for some old profit-generating ventures to become unprofitable. And many will evolve and transform into other markets -- we don't have illuminated manuscripts now, but we do have mass-produced beautifully illustrated books, so in general the printing press seems to have been a pretty good trade and enabled more markets than it destroyed.
