I love to see free speech absolutism being so unshakable.

Even then you can still have someone read the source and write a spec for a second programmer to write a library. The programmer never saw the source code but it was still useful. Still legal to do this. If someone dumped original source into the projector could be similarly checked for duplication without breaking the law.
