Is Housing a major feature of the game?

[Jaibamon]

Not everyone can have the same experience playing the same game. There are some things in this game that not every player can experience. From temporary events, to the challenge to beat one piece of content that it has become very easy to beat today thanks to power creep, or like not being able to play with some of your friends because they are in a different server, or like not being able to get some item because it was tweaked or removed.

Housing may be one of these things, where not everyone can experience. They're limited because the game itself, is design and the infrastructure the game is based upon.

BUT... this time, Housing (specially Shirogane) was featured as what it seems it is a mayor feature of this game. It's on Stormblood's product page, and neither that page or the entire FFXIV site specify the limits and availability of this feature. Any new player would assume they can get a house by just buying Stormblood and actually, Housing is one of the few elements of the game that is both persistent and not available for everyone.

So, is Housing a mayor feature of the game? Should anyone be able to get a house? And how this can be changed without negatively affecting players who already have one?
