Anything is worth money, every little bit counts.
I'm making plenty by simply making much used consumables with my culinarian and alchemist while only spending a couple of hours farming and crafting per week.

I'm not making millions, but with the added gil I make from dungeons (about 1 per day) I make enough to get around with gear repairs, teleporting and leveling up my next craft once my Leve allowance is high enough to take the next one from 20 to 50.
