You have a chocobo stable outside the apartment, there is a moogle mailbox in the lobby, you can have 2 flower pots for gardening and the 1 aspect you'd be missing is cross breeding to which I think can be solved with a multi plant housing item. To this end, the absolute only feature you are missing are airships and workshop crafting, and for this, you need a Light party of other crafters. You can't do it alone even if you want to. So to that end, join a FC with a house.
Some people don't want to join FCs, I get it. But- you have to party with people anyway, so 30 seconds of interaction is not an impossible concept if you really, really, really want those items... which can be sold on the MB. So in fact, you don't even really need the workshop because you can just buy it.
Am I missing anything?
