Copyright is not a benefit to society.
Copyright doesn't encourage content production, it actively discourages it. It doesn't allow anyone to do anything they couldn't have done without copyright, but forbids you to do a whole bunch of things you otherwise could. And even what's constituted "fair use" is often practically impossible because the various draconian enforcement schemes (e.g. Youtubes ContentID) don't understand the concept.
Copyright doesn't give anyone any rights. It takes rights away from everyone other than the "rights holder". It doesn't protect, it punishes.
Beware of the newspeak.
