I can understand how he would see 'framing' as copying a website into another page. But he goes on to argue that we accept this form of 'copying' because of the same 'a visual change is experienced as a physical change' mumbo jumbo.

There would obviously be legal ramifications if you embedded the page into your site then removed their adds and replaced them with your own.
