All of these things give you gil...
Yes, a handful, maybe enough to cover future teleport. How about everything else that needs money in this game?
I live on a relatively inexpensive server I believe, a piece of gear for a fresh 80er costs around 50k each. Depending on job, you'll need 12-13 pieces, which means 600k for each role brought to 80.
Now multiply that with category, like Fending, Aiming... even just 2 categories put you above one million.
It doesn't end there, there's more money to spend to get where you need to be, and then you didn't even sink one gil into stuff like glamours, even just dyes or hair styles, which are a major part of the game and the reason many people chose XIV over other games.

I really rather not spend more money on something like Aetheryte teleports, but I'm aware that this forum is an echo chamber, and arguing won't get me far, so I'll stop here and wait to see how it turns out.
