Look at this.
It's just a single example, there are endless songs which are samples of samples of samples... Once in a while YouTube content id will have some problems as it's not perfect. It doesn't mean the system is fundamentally flawed. Like saying every car on the planet is cursed because once you got a flat tyre.
Only the rich and powerful or those willing to go deeply into debt are able to benefit from all of that extra research.
Pay attention because the alternative to patents is not a "free for all" approach , it's industrial secrecy. As research is still very much expensive for entities to carry out.
Set aside than, no, extra research benefits everyone in the society as new cures for diseases are discovered faster and medicine evolve organically. Patents were the compromise to ensure companies could monetize their research while sharing their knowledge, are there other possible equilibrium? Sure, but we still have to remember we live in the real world, you can't have a cake and eat it
