I mean they could give you a mini aetherite at a later point in time. Which is what you need in order to directly teleport to a house of any kind. Otherwise you have to use the town's aetherite and to teleport to the ward you want and then choose the closest mini aetherite. This feels like complaining for the sake of complaining. Heck even if they don't give us a mini aetherite they could later on allow us to teleport to our island sanctuary from the one in Moraby Docks. Doesn't this sort of help populate the open world? Even if you don't see a crowd at the npc I'm sure a sprout would occasionally see someone use the npc and wonder what that's about.
