No, I don't get it. When a large corp steals music from a small musician, they already get all this, and copyright doesn't help with the situation. Disney has been ripping off independent artists and musicians for decades with no consequences. Ffs even Robin Williams struggled to get paid by them.
At least, for now, people can resist by suing, without fearing unfairly being punished. However, punishing for making false claims will suppress only the weaks by making it harder to sue powerful entities, as they'll get doubly punished for failing to prove their own rights.
OK. But this is a problem with the legal system then. If you give people legal rights to sue that they can't actually exercise because it costs too much, then that's a different problem from giving them the legal right to sue in the first place.
You're basically saying "no-one should get any legal rights at all because rich people will always win any legal dispute". I'm not saying you're wrong. But it's a different problem.
I'm not sure what situation you're describing?
