Why is there still no good solution to the housing shortage?

You lose the wards, but you double up on all of the individual instances

This is what you're asking for when you ask for instanced housing in FFXIV. Just so you know.

That's not what I'm asking because this is not how it works. Do you get in a queue to enter an FC room or personal apartment? It would be the same principle.

Also, these instances can be shared, the same way they already are on some internal spaces in game. I gotta thank Shougun for answering better than I could, even giving an idea of how it could work if implemented.
