While yes, the canon game world is expanded to be huge, I maintain here that the actual ratio of resources holds strong. So, if the entire world is nonupled and there are suddenly 189 rune ores available and 3969 adamant ores instead of 29 and 615, rune ore is still 21 times more rare than adamant and therefore 21 times more valuable.

Also, having a greater literal volume as a result of expanding the world in this example doesn't affect the value because everything else also multiplies by that amount - such as geographic distance, trials and effort it takes to actually retrieve the ore, difficulty of locating a miner masterful enough to extract it (and who is willing to go with you), people with whom you will be competing with to obtain the ore, and so on.
