OP, I wanna try to help you- really. The low post count and combative attitude scream troll, but I want to give you the benefit of the doubt.

So, in case it wasn't abundantly clear:

Yes, you need to have gil to do very stupid things in this game, like pay for transit or pay for repairs (if you're not a crafter). There are very few other places where gil is actively, regularly leaving the economy at a steady drip. You could argue houses or glamours, but that's still nothing compared to the gil being generated.

There are tons of options to make gil a non issue, many of which are passive and require very little effort. This is a far cry from my FF11 days of spending a week farming onions just to buy a new belt or whatever.

If you can't find ways to cover your daily costs, find them. They exist. I've very metaphorically "lead a horse to water, but I can't force them to drink".
