unfortunately housing just isn't a major necessity in the dev's minds, they could easily devote time and resources to re-working it so that everyone can purchase and own a private living space of some kind without fear that they will never get 1 because of limitations. but as Yoshida mentioned before in an interview passed "if we were to go back and re-do old content then this would sacrifice the development of newer content." meaning that if we really want this to happen and be re-made we have to sacrifice a new raid,primal, dungeon, or other type of new content to make it happen.
