So in the most recent duty commenced it was said that we pay for aetherythe transportation to repay the debt the city states made by reconstructing the aetherytes.
Now you might say that the WOL is the only one using these things but it's clearly said in various dialogue that your adventurer companions need to join you, and I doubt they will walk from Limsa to the dravanian forelands. So more people are using this service
Economists might disagree with the following but stay with me for a bit.
The wealthy men of Uldah ( I presume these to be the Monetarists) funded the city states for rebuilding the Aetherythes thus creating a gigantic loan which the adventurers pay off by paying for the teleportation either before leaving or after arriving.
Let's say that in-game time story wise only a year or two has passed(and not go by the day night circle of eorzan time) since we started our adventure in Eorzea.
The amount of teleportations done is going to be a very big number in this time span.
Even if we only had to pay 100gil per teleportation, the amount of gil payed should have been enough to pay back these loans + the interest.
If that is not the case then the amount of gil funded by "the wealthy men of ul'dah" is so big that we could never repay this amount. If that is the case then I hypothesize that the total wealth among adventurers is not even close to the amount funded.
In that case there would be such an amount of gil in circulation that the value of the gil would be next to nothing.
Please i would like to hear your thoughts on this
