Hrmmm, they don't have to hire people like Robin Williams and Tom Hanks to voice act, and it would make the game much more immersive imo. Voice acting please.

As far as making money, they have sold alot of copies of FFXIV and I anticipate that they will start charging money at some point so the voice acting would be one more reason to play this game. A good investment if you ask me, adding to the richness of any story line which FF is famous for.
