Not gonna lie, since I'm not used to anyone who calls the currency of FFXIV "gold" I thought you meant you needed faucets for your house and I was immensely confused by your post until i realized what you meant. (not a big MMO player outside this one lol)

There are other ways not mentioned here that don't involve crafting. If you are really desperate for gil or gear you can desynthesize (which someone else mentioned) or more. But you can't really make good gil/gold without the Market Board in this game sadly. I think the easiest way to make lots of gil without the MB are treasure maps, but the ones you want can't be obtained until level 60+. And once you can get them you can get a party together and see how far you can get in the treasure map dungeons. If you get at least 2 levels down each run it's like 20k per run minus whatever you get in there you can sell on the Market Board. At least I think so.
