Pay for your inventory.

The main issues are more the fact you can send them out on ventures, and the fact they can each sell things.

But you still have to earn the ventures to send them out, which means lots and lots of grinding leves, FATEs or dungeons. The more retainers you have, the more ventures you need in order to dispatch them all.

Yes, I agree. If you were a master crafter/gatherer, using Delivery quests and trading Grand Company Seals for Ventures may be another way, but this also would not scale by adding more retainers. In this sense, using alts would actually probably be more efficient (since they each have their own daily delivery quests, and also have their own allotment of leves, etc.). Plus, as was mentioned, you'd also have to gear up all the retainers with gear, and at the higher levels this isn't inexpensive. It's possible, but not easy to do. And really, the main point I was making was that it's already possible now via an existing method anyway (using alts and an FC, or a second service account).

Ventures are cheaper than dirt. Literally.
