I started thinking about this when I was having a hard time placing price tags at some of my modded items.
I think money is strange right now. Play the game a few times and you sure will find an easy way to be swimming in gold. At late game, if the player wants, he will buy anything at any price. Having an item with a high gold value does not make it more valuable than other items. High prices can only affect new settlements.
I usually play with self imposed challenges, mainly these two: no damage to the terrain and no hoarding, producing only what is needed.
Talking about money, it means that I do not have excess items to sell, and I have to buy stone and metals all the time.
Even this way I still have excess money, which I usually burn by buying wood instead of cutting trees. Also some novelty items, like mutton to be cooked.
