Hardly any of that content would exist at the quality level you are accustomed to, without copyright.
I say that as a producer of such content. If anyone could legally copy and distribute my work without my permission, I would not produce it, because there would be minimal financial incentive for me to do so.
The current level of such unauthorized distribution - by which I primarily refer to the republication of my work by others, in its entirety, for their own profit - is staggering. And that is with the existence of copyright law.
And it’s a huge disincentive from publishing more content. Both economically and because it’s demoralizing.
It’s also a huge waste of time, as in order to be able to pay my employees and myself, I have to dedicate time to combating infringement-as-a-business.
If copyright ceased to exist, I and nearly every other producer that I know, would find another line of work.
Fortunately, copyright ceasing to exist is unlikely to happen.
For starters, the wholesale abolition of copyright would violate the United States Constitution.
