If someone doesn't want to do Y, then let them do X so that they can obtain Y.

In this case, if someone doesn't want to invest into crafting, then just invest into other facets of the game. Literally every single facet in this game awards Gil, or something that can be exchanged with Gil. Running ex primals? Cool, loot on everything, and then Desynth it (Only requires Level 30), and then sell the items you get. Running maps? Cool, sell the items with that. Running exploratory content? Cool, sell the fragments and logograms, or farm other items from there for Gil.

The only stance I can remotely agree with is the purpose of weekly lockout/caps, e.g., with Tomes etc., - One of the biggest selling points is that you can do everything on a single character. Lockouts and caps are an antithesis to this philosophy.
