back to first principles. We have wishes and desires. If we can't get everything we want in quantities we want then we prioritise. I want good food, some mobility and a lot entertaiment. Oil is needed for mobility. Take the average over priorities of the population and you know the price for oil. Markets are just there to determine desires/priorities of the population.
I agree with all of this, when I said "nothing" I meant just that "intrinsic value" is not what determines the price of something, in response to the parent's assertion about intrinsic value setting a price floor on oil
