Unfortunately, the "right to charge" is something that is almost unenforceable in the day of the internet. If you base your business model on this idea, you will spend a lot of time fighting a losing battle against the fact that information is freely exchangeable around the whole world.
Photographers don't sell copies of the photograph to the general public. I don't think most photographers are actively trying to fight, say, you printing out the photo and hanging it up on your wall.
The original blog post was about licensing works - major magazines and publications wanting to use the photo. This is entirely enforceable - these magazines and publications are headed by companies that one can actually discover and sue.
The "right to charge" is alive and well, in the same way the GPL is enforceable.
