Of course DDT, nails work to a point because they are decently light. But there is still not banks offering fixed value exchange rates. The more regional, and the more of them that there are, the stronger the currency will be.
Rocks are a terrible currency I'm sure you know why.
The point of this system is to make it very easily exchangeable, and to have guaranteed exchanges. Yes nails are easily exchangeable due to being light, but unless you are using a cart, you aren't going to go around carrying much more than 10k nails. Especially if you are not a high STR player.
