A very rich man wanted to be generous, so he made several copper keys that would allow one to access his treasure.
He told this to the people, but most of them did not believe him. A few believed him, and became rich, but people did not believe them, either.
Then the rich man made a golden key, essentially a copy of the copper keys. On seeing this, the people fought among each other, not for the fact that it could open up the treasure, but because the key was made of gold.
"Isn't it absurd?", the Master asked.
