The virtual currency "Moogle Coins" in the FFXIV Companion app must be removed

but you earn them every day you log.

No, you’d earn kupo nuts, at a rate of one per day. Two if you subscribe to the app. I’m assuming that one would only allow you to manipulate the mb once, similar to how one venture only allows you to send a retainer out once. I can’t say whether this allows you access to a retainer so that you can change multiple entries on a single retainer, or if it only allows you to change/add/remove a single item (likely the latter) but either way you’re extremely limited by one or two nuts a day. That’s where the coins come in; you’d theoretically be able to purchase an unlimited number of those and use an unlimited number per day, and they’re only available for real money.
