The gist of his argument is that the Internet is just technology. It’s how we use this technology (for things like speech) that is the human right, not the technology itself. That’s the wrong way to look at it. New technology adds new complications that require clarification.
That's what happened with the printing press. Our founding fathers chose to enshrine technology in our Bill of Rights, by saying that “Congress shall pass no law abridging the freedom of the printing press”. The invention of the printing press revealed new rights, new concerns nobody cared about until the printing press appeared. It's difficult trying to list these new rights without reference to the technology that enabled them. Instead of "right to publish", it's just easier to simply say "right to printing-press".
