I agree I wasn't super precise, I thought it was enough to show that pricing work equal or close to equal to value produced is unlikely as long as there's many people available to do it. In my example of the fire department if nobody is really coming and you have no insurance or other way to save stuff you would indeed pay a lot. From what I read these were the dynamics in Roman times.
