1.0 had a teleport system similar to what you're talking about, where you could teleport from an aetheryte to an aetherial gate (kind of like a natural aetheryte found deep in each zone), but this is no longer available because, the original aetherytes were different in shape, they cost not gil to teleport but a consumable (and slowly regenerating) stat called anima, zones were so much larger than they are now, and that there were far more aetherytes available. Now there's usually only a single aetheryte per zone (and no aetherial gates either).
