Things don't have any inherent value. It is priced at a level that a buyer thinks it is worth.

A gallon of oil can be $3 or $6 depending on whether someone is willing to pay. It can also be $10 but only if people are willing to buy it at $10 if not "prices will come down to match the demand" - another way of saying it would be $9..$8...$7...$6 until it matches a buyer at which point gas is $6.

This is what I am trying to express. There is no "inherent price" or "inherent value" there is only the real value that it is bought at (in terms of money). There can be other values (non money) like if someone is willing to swap something for it etc.
