Real question, say you have no interest in buying a house, is there reason to hoard gil?

Until recently I was busy gathering/crafting to make as much money as possible in hope that I could use it to buy or make something for my DoW/M classes. Turns out that is not in the game design, so I've stopped crafting/gathering for profit. I've become the DoW/M you want us all to be, grinding the same dungeons for Philosophy/Mythology which means gil is just an on screen artifact left over from a time when it had purpose.

I know, rich character problems.... but still if you have a ton of gil what are you holding onto it in hopes of?

I'd love to give some other person who did not make money crafting some of this currency for some rare dungeon gear I need. They could then give it to someone for some rare dungeon drop they need and the cycle could keep repeating itself.
