It sounds like a lot of people in the world might consider the treasure to have been stolen. Who is searching for a treasure that doesn't seem to clearly belong to even the person who buried it?
People are dying for this treasure, which was created through "controversial" means while a 'self-taught' archeologist was digging around. It seems he clearly had no formal training in morals, may not have been accompanied by others, and very well may have stolen the entirety of the treasure from potentially rightful owners.
Seems like not a treasure worth dying for to own. Chances of becoming a millionaire by starting a business and working hard for many years? Somewhat reasonable, probably.
Chances of dying looking for stolen treasure? Not worth it.
A man died walking down the street in New York because a piece of fire escape fell off and hit him in the head. I wonder if he'd rather have died in the wilderness, if he were given the chance.
