The issue is that if the barkeeps are charging the adventurers three times or a hundred times the amount of money the beer is "worth", that still doesn't change the fact that the beer has real value and the gold the adventurer is paying in has only symbolic value. So the barkeep and the town both have their real assets reduced when the adventurers come and buy their stuff no matter how much the adventurers pay.TarkisFlux wrote:Why is the default assumption always that coins and gems accepted from adventurers make their way into the local economy? Why can't merchants and barkeeps just charge adventurers 3-10 times what it actually costs for the items or service and then sit on the difference so that they can rebuild when a monster or adventurer inevitably damages or destroys their stock and shop? Whether it's collected by a tax man for the good of the colony or stuffed in a mattress for the good of the owner, money that is saved for rebuilding after the latest adventurer failed to succeed a rainy day is money that is not crashing the local economy. It's not like there's a source of credit for peasants to use as an alternative to hoarding, and you potentially need a lot of capital to pay off traders and whatever to bring you material / stock after such a bust.
The only way this can be a net positive is if the villagers can then turn around and purchase goods and services with those coins that they otherwise couldn't. And for that to be the case, the economy as a whole would have to have the capacity to make goods and services which it is presently not doing because there isn't any demand (that is: there isn't currency to buy it, so the resources to make it are left idle). In short: for "random adventurer walks into town with pockets full of gold" to actually be a good thing, the economy has to be perpetually depressed in a way that simply running printing presses could solve.
Which is perhaps unsurprising, because adventurers walking in with pockets full of gold pieces they found in a distant hole is roughly equivalent to the Federal Reserve getting up and printing a fuck tonne of hundred dollar bills for shits and giggles. In any sort of "full employment" situation that we would call "normal", that would drive up inflation and be basically bad for the economy. Only in a deeply depressed and currency starved economy could that be a good thing.
