This doesn't fix housing. I am not sure what it will take to get people to realize this. What this does is adds instanced housing.
Let me put it this way: You run a donut shop, and you cannot meet the demand. Instead of figuring out how to fill that demand, you decide to also buy a bagel shop that can fill demand [for bagels]. Now you're dealing with customers who want donuts AND customers who want bagels. Some customers will be fine with a bagel. Others will decide they will take a bagel instead of donut. Other customers will say, "I want a donut, not a effin bagel." Other customers will say they want both a donut AND a bagel too, and they should be able to have both if they are willing to pay the money.
You create a 'grass is greener' situation for the bagel people who still don't truly have all the benefits of the donut shop, while the donut people get to have both donuts AND bagels because the owner isn't crazy enough to demolish his/her extremely profitable donut shop.
No one wants to hear that housing will always be limited. It's just the nature of the beast. The only way the dev team can make things fair for everyone is to eliminate housing in its current state. FC housing is an entirely different animal that quite honestly should have absolutely nothing to do with private ownership. They could change things up and make all private ownership instanced, and all of current housing would then be restricted to FC access only. However, even if they could do this, there will still be an angry mob of players steamed about never getting what they truly wanted. There will still be homeless FCs. And there will also be a lot of private owners who will still feel like they lost their home even if it is kept entirely intact, when it is thrown into virtual solitary.
There will come a time in the game's lifespan where there will no longer be enough players to fill all the wards, especially if they keep releasing more of them. While I am quite sure this doesn't do a whole lot to provide any kind of consolation for the shortcomings involving housing, it still remains an eventuality. That doesn't mean that instanced housing will never be a thing, but it needs to be understood that instanced housing is not current housing. It is entirely different content.
