I think the "building in public" approach has been a failure though. Unreal Tournament didn't work. Crowdfunding can work, but I think people probably are leery of that for larger projects or studios without a track record of success.
And with a project like Unreal Tournament you're not going to get the flood of hat money and other MTX bullshit that currently feeds studios. Even if you want to pay for a game pass, I can just give myself the game pass on my own local copy, and get all the same stuff right?
I'm not entirely saying that (Jim Sterling voice) "triple-A gaming" dying is the worst thing in the world mind you, but, we'd be talking about some really tectonic shifts in how things get built and I think the pot of addressable money is really a lot smaller.
Hopefully it would lead to more passion projects and not just the death of the industry.
Like I said I think patents have been a scourge, but copyright in the sense of owning the thing you wrote, is less problematic. Derivative works are the problem case that I've previously talked about though since I think humans go through our world deriving and remixing everything we see and touch and that's not a bad thing. And AI is going to make all of this very problematic in not-very-many years either, 5-10 years and AIs will be writing great software and making great creative works without significant human intervention.
Once we move past capitalism as a concept, then yes, by all means these things can go away too ;)
