What do you mean by this?
In retrospect my choice of the word "material" was vague. I'm referring to intangible creative works.
Let's work with a metaphor: nobody pays for air. It exists in sufficient abundance with sufficient availability that there's no reason to. But you could, hypothetically pump trillions of tons of toxic gas into the atmosphere, build a bunch of domes with clean air, build a
limited number of air purifiers, and then charge for breathing your clean air. By creating artificial scarcity for something that was otherwise available in abundance, you create a market for it. And if you grew up in a society where paying for air was the norm and suggested to people that it would be possible to have a society where air was free...no doubt they'd ridicule you and ask who would pay for it on your behalf, how could you expect people to do the work to make the clear air available, etc.
Copyright creates artificial scarcity for intellectual/creative works where scarcity does not otherwise exist. This is its purpose.
If I bring an intellectual "creative" work into the world for which physical matter is not essential, it exists in that same sort of "sufficient abundance" as air. I wrote this thread post, and dozens or hundreds of people can see it at no additional cost or effort from me. You can copy it and reproduce it endlessly for trivial effort without taking it away from me. The same is true if I write a song, or a computer program, or take a digital picture, or make a movie...any of these things can be endlessly copied by others without taking it away from me
Anticipated response:
"Oh, but if you copy/pirate creative works, then you're "taking away" the opportunity for the creator to make money from it."
Yes, but that opportunity only exists because of the existence of artificial scarcity created by copyright and social stigma. You wouldn't suggest that I'm "taking away your opportunity to sell air" by discouraging factory pollution. It would be a silly argument. You wouldn't make it. The only reason you don't see copyright as a silly thing is because you've grown up in a society where it's the norm.
Now, yes...there do exist creative works for which there is significant cost to their creation. Obvious example: most movies cost dozens of millions of dollars to make. But,
that is only so because we exist in a culture where the arbitrary convention is that movies are sold. There's no
reason for that convention to exist except solely so that money can be made to change hands.
There is fundamentally
no reason for copyright to exist except to enable people to artificially create scarcity in order to encourage the exchange of money.
Why is this a desirable goal?
Anticipated response:
"Because if people can't make money for what they do, they won't do it."
This is obviously untrue. Even in a society like ours where copyright does exist, there are still creators freely producing content because it's what they want to do. Yes, people sell books, but nevertheless people write and make their works freely available. Yes, microsoft makes and sells windows, but nevertheless there are people making and freely distributing operating systems. Yes, studios produce and sell porn, but nevertheless there's no shortage of it online. Music, art, software...take your pick, there are people out there making it because it's what they want to do and giving it away because they'd rather their work be appreciated than not.
I simply ask: if people will produce these things because they want to, because they enjoy it, if you are taking nothing from them by making copies of it...why is it better to create artificial scarcity and require that money be exchanged for it?
