Do you really think they have the resources and time to make land and specialized housing for the influx of adventurers not even from their own shard? We're on the First to help their home recover not build another Eulmore. On top of that, the Crystarium is not a fun-time adventure housing ward. It's a city of refugees. We're lucky to even have a room of our own considering how many people go there to seek shelter because they have no home of their own. Not to mention as someone above said, hundreds are turned away because there is no room in the Pennants.

There seems to be a pattern of people wanting a housing ward in places that canonically have literally better and more important things to do than establish a housing ward for foreign adventurers. You know like Ishgard and, though no one has asked for it but I'm sure someone somewhere has thought about it, Ala Mhigo.
