Its just a static background, and even if its an entire city, it doesnt matter since its localy rendered.

Other than that, housing interiors are already instanced. The limitation is how many houses can be loaded (and the number of players that can be inside a house at any time). Thats why you can have many appartments. Its only the outside that requires the ward to exist. And yes, this can in theory be part of an instance. But this brings you to the next issue: teleportation.

Whenever you get teleported to your house/appartment, you will always teleport outside to the general ward. And the simple reason for this is: your instance might not be available. The general area on that has plenty of space to support your player slot (and while in a duty, can keep that spot reserved). This doesnt work for the inside of a house as that would severely waste resources at that point. Its even that bad, that some instances are coupled to a seperate area (like skybuilders), to prevent the issue that a player cannot teleport back to where he was.

There are very likely even more restrictions here, but this should hopefully give you a better idea on why it works the way it does now.
