Servers with smaller populations may still have lots left, which leads to this elitist "you should just switch servers" mentality some people have. The lack of houses wouldn't really be a problem though if it was simply side content for fun with no actual bearing on gameplay. Unfortunately, SE has decided to lock certain content behind owning a FC or personal house, (at the moment, raising a chocobo beyond rank 10 or dying it's feathers a different colour), and soon this will only get worse once Heavensward is released, where the player needs to build an airship to access new expansion areas and participate in upcoming content (airship battles?) - which SE has said can only be done by using a basement attached to a house.
Now, if they brought in an alternative means to access this content (like, a communal chocobo stable for raising chocobos without a house, or an airship workshop run by Cid to build player airships), this would solve this potential problem. But right now, as it stands on Legacy servers like Balmung where there are no free plots at all, there will be the very real risk that a significant portion of the player community will be locked out permanently of certain content -not a good thing for a game that is selling itself as a game for casual players.
Either way, I really hope Yoshi and the development team have another look at this serious issue and find ways to address it, if not by adding more wards then maybe alternative means like the ideas I suggested.
