I didn't break the rules, I just took the rukes for lowering HP with a sword and made it raise HP.
That is a gross mischaracterization of what I'm talking about. It took the rules for selling a thing, and I acted as though I was selling that thing. There was no inverse of the math, just a change from who was receiving the money. You might as well tell me I did something wrong because I took the damage from a longsword against an NPC and applied that same damage to a player.
In the real world I cannot sell almost anything for what a store does. A d the cost of selling stuff in a store, quite often the cost of the goods sold is not the majority of the cost (efficiency is highe now in this age of low friction commerce).
Really? So... how do stores sell things if it is impossible for people to sell things for the same price of the store is selling them for? Do they operate under different physics? Are there not humans who are selling things at stores?
What you are really talking about is that you, person in your basement, can't match the efficiency and infrastructure of a major distributor. And, there is nothing like that in DnD worlds. There is nothing at all listed for saying that spellcasters are part of a major, global organization that allows them to charge more or less for services. In fact, generally in DnD it is presented as... a single guy, possibly in their basement. Exactly the situation you are saying can't work.
The rules cover what PCs can expect to pay for spellcasting, roughly. Tge rukes do not say PCs can expect to find customers willing to pay that and at what rate.
Maybe that rate produces 1 customer per year for someone who sets up a wizard tower in a major city and is known throughout the lands. Then this matches the price PCs pay, but means selling such services is not very profitable.
Maybe the right to sell spells is predicated on providing spellcasting services to the state for free. And only with limited number of excess spells can you sell to3rd parties, for which you owe a 90% tithe. So the nobles aren't buying.
Again, PC prices look the same, but seli g sin't profitable.
"I just flipped the rules" does not mean you followed the rules.
And all of this is just attempts to say "No, you can't make that money, I can't allow it." But again, no one is telling me why. Why are you so terrified of PCs making significant money during downtime? What harm is this doing to the game? Why do you think we can't have an adventure if we happen to be wealthy?
