Well, what did you expect, from a mindset is not attached to physical reality?
That it would make any sense at all?
The wall with the graffiti is a physical object.
A paper photo in your hand would be a physical object.
But neither the graffiti itself, nor a photo of it, are physical works.
They are ideas/information. Other rules apply.
“Licensing”/“copyright“ is a concept, based on the misconception that ideas/information would be physical objects, and the false need of some people, to control that information.
Trying to argue with it, using logic, is (because of that false base assumption) by definition impossible.
The real physical rules for information are: If it’s out there, it’s out. Period.
So you either never give it out, and won’t be able to prove that it exists at all. Or you give it out to your chosen group.
Which can for example be people that you trust. Or, as in this case, everybody.
In case you gave it to everybody who wants it… well, you should have thought earlier about that everybody could store and copy it at will. (Just like looking at the physical wall and then telling someone, or drawing it from memory, is storing and copying.)
It does not matter if people want to accept that. Just as it does not matter if people want to accept gravity.
You can try to enforce weird rules of behavior onto people, trough mental tricks of psychology. And it may be easier to do in this case, than it is for gravity. But in the end it’s futile. Because you can’t control the whole world. Even with ACTA.
If nothing else, you will end up banning the ability to look at it, because some people became really good at memorizing and reproducing it later. And everybody who can’t remember it, will by definition not remember that it existed.
Whenever anyone mentions “facts”, you know he tries to shove his dogmas down your throat.
