But it's totally necessary; back before it existed no one ever made any money for their creative works, so with no incentive no one ever made anything creative before copyright law. OH WAIT.
2. this is disingenuous. it is already the case that the massive majority of artists have a very hard time generating a sustainable revenue stream from their work, and this has always been the case. the goal of a copyright system is, amongst other things, to try to help with that.
2. So with copyright it's super hard for artists to live off their work. How is that defending copyright? If you're claiming "Well, it'd be even worse -without- copyright!", you haven't actually made a case for that. Certainly, if we want to fix the fact artists have a hard time, perhaps an alternative monetization scheme, irrespective of copyright, is the right answer?
Who, specifically, is that 1928 copyright still encouraging to create new media? How does it benefit society more to have insanely-long copyright terms than it would to free up creations earlier for riffs, remixes, and so on?
The original idea was that copyright is a compromise that maximizes the social welfare, people give-up their natural right to copy and share for a limited time so that more culture is created. Of course, once the system was set in motion, the holders of valuable works had a very strong motive to exert political pressure to extend the copyright to absurd lengths and push the notion of "intelectual property" at face value, instead of the original social compromise. No one was left to fight for the public domain and now we have these huge dynastic corporations that are strongly anticompetitive, using warchests of past works that new creators haven't yet amassed. If not for the internet and long tail consumption it enabled by lowering entry barriers, a few companies would own all comercial culture.
Seriously, I tire of this notion that discussion must be dry and boring. Holding discussion hostage to "don't say anything that might offend, police your tone, and say everything as plainly and factually as possible"-type rules allows intellectually dishonest participants to game the system, i.e. bullshit asymmetry. Clever use of rhetoric is an effective tool for highlighting disingenuous arguments. In this age of information overload, we need it.
