When will you really address the housing availability problem?

When? Never.

This is, unfortunately, more or less accurate.

Though they've stated that they plan to add additional housing wards in Ishgard, shoehorning personal housing into the FC housing system (rather than following their initial intent of making it a separate system) pretty much guarantees that there will never be enough houses available for everyone who'd like one to have one.
