Wrong, power smithers and rich folks will never get around to mining their own ore, when there always is a new generation, a new generation willing to slave away in the mines for a measly 100-150 gp per ore. I don't know where your coming from, but the prices of coal have been more expensive before, in fact most items in Rs2 have dropped in pricing. Mainly because of the obtainability of the item becoming far easier, and quicker.
