I know for a fact that some treasure contain traps. Some treasures have a curse on them. But..Just whom is going to enforce this curse? When someone is dead they do not have the power
Art: For the most part, you are spot on. But it all depends on the characteristic and components of the curse and the degree of ignorance or knowledge of the listener. Indeed, when the author of a curse is dead, so is that curse, unless it is like the following example of a so called: "curse" This one will last, simply because of how it came into being and the ignorance of the listeners, yet the author of the curse has been dead now for several centuries.
In the days of the Spanish explorers here in the Americas, when they processed gold ore, arsenic was produced. Arsenic is toxic. An Indian medicine man understood this fact and after placing some gold in the mine, he sprinkled large amounts of arsenic on the floor and mixed it in with the dust. Knowing the people in the village were ignorant about arsenic, he said: "I have put a curse on that mine shaft, so if you go into it, you will die!"
There is a real treasure in an old abandoned Spanish mine shaft in western New Mexico from which this story comes from. Around 1969, three men went after it and all are dead now. One died two days later in an Albuquerque hospital from undetermined causes. Because they had to crawl on their bellies to get inside the old mine shaft, he had breathed in large quantities of the dust which was saturated with arsenic, which the medicine man had placed there. One went crazy and was killed later while committing a crime in California. The last one lived a fairly normal life but later contracted lymphoma cancer which arsenic is known to produce. Being very depressed about it all, he got into his car and drove into the Sandia Mountains. At high speed, he missed a curve, went over the edge and when the car hit the bottom, it created a forest fire that took fire fighters three days to put out. End of story.
So, put on a face mask with a breather filter in it to keep from breathing any arsenic, put on some gloves and completely cover your self with a suit to keep your skin from absorbing the arsenic and go inside the cave and remove the gold, leaving the arsenic and the curse where they lie. But, just in case and to be safe, after you come out, take a long shower.
