I'm pretty sure musicians made a living before there were recordings of their work to sell. Some by performing, some by having a sponsor, etc.
People should be able to make a living off of their work without someone stealing it, as in your book-writing / publishing example, but the idea that a business model based on selling recordings (which has only been possible for about 100 years) is the
only way, and is somehow an inalienable right of the music / film industry seems frankly absurd. I'm not sure what the "right" answer
is, but I'm pretty sure that attempting to impose artificial scarcity on an abundant resource (digital copies of recordings) and 100+ year copyright terms is not it.
Also, as always in this debate :
a handy guide . Please keep terms clear.
I must say that I agree with Nes's quoted point. For me the most concerning thing about copyright infringement is that it's so easy and commonplace and severely shouted that "THIS IS A CRIME!!!" everywhere that we're teaching a whole generation that the law only matters if you're really going to extremes or if you get caught, not that it's a valuable institution that makes society possible.
