Because Home is where your Aetheryte Teleport is waiting for you.
Aetheryte are massive shards of crystallized aetheric mist in Final Fantasy XIV, precisely cut and fused to arcane machinery. While it is not known when or by whom these devices were originally constructed, their teleportational qualities have become the backbone of everyday transportation throughout the realm, with most managed and operated by individual city-states.
Based on Square Enix's Final Fantasy 14
