...if you take a step back, that's the point, it's by design. The limited access is a feature not necessarily a flaw.
It's like the ishgard restoration competitions. There are only 12 spots at the top, for the 12 most dedicated players. There's only housing for 30%-50% of the most dedicated players...
I can see where you're coming from. But then SE needs to bluntly state that persistent ward housing is not for every player.
