I think it would be a waste of resources since it seems only a tiny proportion of players want this.

I confess I have absolutely no interest in world pvp at all. It sounds like fun in theory, but reality (going by WoW experiences) is that new/low level players get ganked and geared and levelled players tend to avoid each other.

In FF it would make little sense from a lore perspective unless significant changes were made to the story and gathering would need a complete overhaul to even be viable. Why go to all that trouble for something the majority of players dislike and won't participate in?
