"The Internet is a copy machine. At its most foundational level, it copies every action, every character, and every thought we make while we ride upon it. In order to send a message from one corner of the internet to another, the protocols of communication demand that the whole message be copied along the way several times. [...] Yet the previous round of wealth in this economy was built on selling precious copies, so the free flow of free copies tends to undermine the established order. If reproductions of our best efforts are free, how can we keep going? To put it simply, how does one make money selling free copies? I have an answer. The simplest way I can put it is thus: When copies are super abundant, they become worthless. When copies are super abundant, stuff which can't be copied becomes scarce and valuable. When copies are free, you need to sell things which can not be copied. Well, what can't be copied?"
