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