copyright the pyramids?

From BoingBoing and Techdirt -- Egypt plans to pass a law that enacts copyright protection for the pyramids and the Sphinx and any object in any museum in Egypt in order to levy fines against creators of full-scale replicas that infringe on this so-called copyright. Apparently the Luxor hotel is safe because it's not an exact replica ...

I understand looking for income streams to care for their cultural heritage and I am extremely sympathetic, but this is such a wrongheaded interpretation of the concept of copyright. That said, Egypt can set their own copyright laws, and if they want to declare this part of their copyright code, they can. I wonder how they plan to enforce this?
