It is a system just like ours, but without copyright. It's a very credible system, as it worked very well for some 10000+ years and gave us epic works of art of every form imaginable: literature (fiction and non-fiction), music, architecture, painting & drawing, live acting, to name just a few.
And how many Hollywood blockbusters with $100 million budgets did that produce?
How many million-lines-of-code software products?
How many detailed, fact-checked, well-edited 1,000 page textbooks?
For that matter, how many good books did it produce per year, and how many people got to read them?
I've never disputed that valuable works have been or would be created without the benefit of copyright protection, but the scale matters. You can't just extrapolate from the fact that some good works were produced and some people benefited from them before copyright to the conclusion that copyright has not encouraged the creation of more or better works.
There is not a shred of evidence that copyright provides an actual incentive to create artistic works, i.e. that fewer works would be created without copyright, or that the overall quality would suffer.
Except for the millions of people employed around the world in creative industries whose rent is paid by income protected by copyright, you mean?
If you are concerned with credibility, you should stop saying that copyright helps to increase artistic output, because, as a matter of fact, it does not.
If it's a matter of fact, then I assume you can cite actual evidence of an alternative situation where artistic output was maintained at the same or higher levels of quality and quantity without copyright?
There were plenty of works created before the copyright was invented, and today we still have high quality works, artistic and otherwise (e.g. FOSS) that are being created every day.
Ah, the FOSS argument. How wonderfully Slashdot.
You've noticed that very few FOSS projects are even in the same league as their commercial, copyright-supported competitors, right? And that even the big name FOSS projects are not exempt from this? So much so, in fact, that even though the FOSS projects are free, most people still prefer to use commercial offerings.
At the same time, there is a bounty of evidence for the systemic abuse of the copyright by the content owners, who find the law helpful for cementing their content distribution monopolies. They do so mainly by hiding in their vaults a good century worth of artistic works, thereby robbing us of the PD and creating an artificial scarcity.
I've never disputed that there are serious flaws with the current implementation of copyright. Arguments about not extending terms to crazy 50+ year durations are all very reasonable. But if you look at what's being swapped on filesharing systems, is it very early Disney cartoons and back-catalogues for old bands, or is it the latest pop tracks and Hollywood blockbusters?
Additionally, you have to explain why a monopoly is good when it comes to producing copies of artistic works. If you agree that markets operate well (from the consumer's point of view) in presence of competition, you have to point out the fundamental difference between pizza and painting.
Well, among the fundamental differences are that pizzas are commodities and paintings are not, that producing a pizza takes seconds while producing a good painting takes days, and that producing a pizza requires throwing some ingredients on a base while producing a good painting requires skill and talent.
Apparently, there is something about distributing copies of a painting that makes a monopoly good, so please tell us what it is. Explain why an artist should have a right to restrict the sale of anything but the first copy.
Because through copyright, many people who benefit from a work can each contribute a small amount of the total cost of producing it, making it a commercially viable project for the creator. Notice that this applies on many scales, whether we're talking about excellent textbooks with limited markets and relatively high prices, or cheap paperbacks that are read by many people for a relatively low cost, or crazy expensive Hollywood movies that are viewed by millions. If the artist can only control the first copy, then the price of that first copy becomes so high that in many cases no-one would buy it, and with that recognition, the work will not be produced in the first place. You're basically back to a patronage model.
If you try to address this issue, you will probably say something about inability to recoup costs in case of big-budget projects like movies, but this is bullshit. You will still have to explain why a monopoly is the best way (for a consumer!) to pay for these projects, while other perfectly sound ways of raising funds are known and used today (citation on request).
Citation requested. If you can show me evidence of even a single successful Hollywood-blockbuster-scale movie being funded through another mechanism, I will be impressed. I will be even more impressed if you can show me evidence (not just hypothetical argument, something verifiable) that the same model would sustain production of the same number of big budget movies as the big studios manage, the same number of major software products that the commercial software industry manages, and so on for other industries supported principally by copyright.
I find it doubtful that you will manage these things, because of course nothing about copyright prevents people from releasing their work and trying to make money through other models instead if those other models were superior incentives. The fact that almost no-one does this is quite telling.
