You didn't answer the question. Did you read past what you quoted or did you not understand what you read?
I read it but the stuff about the high level game where resource recovery isn't as big an issue isn't really relevant the what we are discussing (a potion based mechanic to replace the rest based mechanic for resource recovery).
I shudder at the state of your table if players need permission to play the game. This reeks of a horrendous GMing attitude.
You can't gather a resource if it doesn't exist, or there isn't a place to gather it form the DM has as much control over that as they do over when you rest, so I don't see how your mechanic removes that issue you have with of the DM controlling resource recovery.
Because its contrived, unrealistic, and isn't fun for anyone, including the DM.
What's unrealistic about a night's rest or taking some time to tend wounds and get your breath back?
You should read more RPGs. And you're overstating what a game economy has to be anyway. This is less Gazillionaire trader sim and more just good synergy between costs and item rarity.
I've read plenty, so please point me to one with a function economy, I've got about 100 on my shelves without.
