As of right now, crafting will help your gil from running dry. Now you may say that everyone can only earn a limited amount of gil before it runs dry. Well lets now look at what everyone is ignoring or failing to post in this thread, the gil sellers. They are spamming 1-50 quest over and over. Then you get someone that waste their RL money on gil for an advantage and that person buys a lot from the market board. The crafters then benefit from the market board.

Now I don't like how this is with gil sellers. But this current system seems to be designed to take in the account of the inflation that RMTs cause. While it would be nice if a mmorpg could completely prevent RMT and automatically ban anyone who even attempts it, the real story is far from that right now(which is sad but true).

So as of right now, craft if you need gil and hope that poor sap who waste their real money will buy your items on the market board.
