While I agree that some copyright law probably goes too far, I don't understand how you could advocate for 0 copyright? What incentive will people have to produce creative works in that case?
>If the resulting software is so poor you need to hire a human specialist software engineer to come in and rewrite the vibe coded software, it defeats the entire purpose.
I don't think this is entirely true. In a lot of cases vibe coding something can be a good way to prototype something and see how users respond. Obviously don't do it for something where security is a concern, but that vibe-coded skin cancer recognition quiz that was on the front page the other day is a good example.
