If you're going to argue people should accept AI code (what people ought to do) then you've entered a moral argument. People are free to argue about when the code is good 'as in useful' but naturally that's not as important as when the code is good 'as in morally good'.
I value software freedom, and copyleft licenses like Linux's GPL for protecting it. While AI generated code cannot be copyrighted then it cannot be licensed under a free software license. It can legally become proprietary. You ought not accept "good" AI code.
