The issue isn’t whether you can create things without copyright. It’s whether you can create Star Wars Episode XYZ without copyright. The answer is probably not, for the same reason you don’t have open source laptops with the fit and finish of a MacBook Pro.
The thing is: absolutely nothing is preventing people from creating content without copyright. So what exactly is the problem? AAA content gets produced and monetized using copyright protection. People are free to use copyleft for their indie content. And at the end of the day, the market speaks and AAA content is what people want. Saying that “getting rid of copyright would be fine except we’d probably get less AAA content” this is completely unresponsive.
The “SWAT team” issue is a red herring. I don’t think we should have SWAT teams responding if my neighbor’s fence encroaches onto my land, but that doesn’t say anything about whether I should have an enforceable property right in the boundaries of my yard.
