Then we agree!
As the Berne Convention Act states that only another building can infringe the copyright of another building, I wonder how far we can take that logic.
i.e. can you only infringe the copyright of a statue by making another statue? A flat piece of paper with the picture of a statue on it is not really a copy of the 3D original.
What about an oil painting? Is a photograph of it a copy which can be an infringement or does it have to be another oil painting in order to infringe the original's copyright?
