When copies are free, you need to sell things which can not be copied.

Well, what can’t be copied?

There are a number of qualities that can’t be copied. Consider “trust.” Trust cannot be copied. You can’t purchase it. Trust must be earned, over time. It cannot be downloaded. Or faked. Or counterfeited (at least for long). If everything else is equal, you’ll always prefer to deal with someone you can trust. So trust is an intangible that has increasing value in a copy saturated world.

There are a number of other qualities similar to trust that are difficult to copy, and thus become valuable in this network economy.  I think the best way to examine them is not from the eye of the producer, manufacturer, or creator, but from the eye of the user. We can start with a simple user question:  why would we ever pay for anything that we could get for free? When anyone buys a version of something they could get for free, what are they purchasing?
