Oh, nice idea. An Intellectual Property (IP, or 'imaginary property')-driven D&D game. I pitched an IP-themed adventure to Paizo, but they passed on it.
If the raw materials cost as much as the list price, then there isn't much incentive to produce goods through this method -- unless the market price is much higher than the game's list price in that locale at that time. After all, it takes raw materials plus skilled labor and, presumably, a large capital investment to produce something valuable through this method.
On the other hand, intellectual property becomes even more valuable. The recipe is all that stands between you and great wealth. Throughout history, that meant hoarding knowledge, but in our modern era we benefit tremendously by sharing knowledge, which is a nonrivalrous good, in economics parlance.
"Intellectual Property" is a very modern concept rooted in modern legal systems and property laws; the closet medieval term would probably be "guild secrets". As you've said, the need to keep the rituals secret would strengthen guilds, but I think that it would make them even more secretive as they already are: guilds would guard their secrets very jealously.Another interesting point: How would a medieval society react when intellectual property suddenly became hugely important like this?
I suspect a strengthening of the guild structures, possibly with guilds gaining a larger geographical scope...
The question is, is residuum deposited in a few key areas, or is it dispersed around the world? And is it renewable, like lumber, or is it made from millenia-old dragon bones?
Scarcity would only be a thing of the past as long as residuum supplies grew faster than the population. (Or the residuum-efficiency of the rituals grew faster, via "technological" progress, than the population.)If the rituals were common knowledge, you would have a more socialist society...scarcity would be a thing of the past, and there would be public houses where people would go to get their food, clothes, toys, etc.
