It doesn't work like that, not with text. If you make a text model smart enough it will be able to generate whatever you want.

With images we could ban models that generate drawings. But then, I'd argue that one creative group (painters) are trying to ban another creative group (programmers) from doing their art. Both painters and programmers should be free to create whatever they wish, unless there is a clear, unquestionable, harm to the society as a whole (not just another workgroup) from their creations.
