I believe PoE devs know the limitation (maybe indirectly) of their barter system, because at the end of each season, they will transfer all the characters and currency into the standard league and start all over again.
So the standard league became stagnant and inflated, economically speaking.
I'm intrigued to see a live-service game (especially MMO) with a sound money design for their economy. Interesting to see how the players react and try to beat the system 👀
