This type of argument is ignorant, cowardly, shortsighted, and regressive. Both technology and society will progress when we find a formula that is sustainable and incentivizes everyone involved to maximize their contributions without it all blowing up in our faces someday. Copyright law is far from perfect, but it protects artists who want to try and make a living from their work, and it incentivizes creativity that places without such protections usually end up just imitating.

When we find that sustainable framework for AI, China or <insert-boogeyman-here> will just end up imitating it. Idk what harms you're imagining might come from that ("get ahead" is too vague to mean anything), but I just want to point out that that isn't how you become a leader in anything. Even worse, if they are the ones who find that formula first while we take shortcuts to "get ahead", then we will be the ones doing the imitation in the end.

Copyright is a dead man walking and that's a good thing. Let's applaud the end of a temporary unnatural state of affairs.
