Also depends on the "mood of the job usage" ingame too. ATM Nin is not the big-bad-ass tank job it used to be like when Abyssea came out, so Ninja Tools have dived in sales and with that, so have profits. Goldsmithing (I think SE loves goldsmithers), is always there for profiteering, for for every one possible synth we get for other crafts, Goldsmithing usually gets 8 new ones, one for each element. (Rare exception being elemental staves, but gold STILL also got 8 different synths same time.) So if the "mood of job usage" changes again and makes other use-and-consume jobs more wanted (Rng/Sam/Cor with arrow/bolt/bullet, or Nin with tools, for examples) then maybe we'll get some viable gil-making crafting done. That can happen or when next round or so of new crafting items get sent out, make them NOT for Goldsmithing, but for those of us with less used/looked-for crafts (i.e. Woodworking, Bonecraft, Leather).
Hint: you CAN make rings out of wood you know, NOT just metals
