Your argument falls apart after the first sentence. I totally agree that Square Enix should work to improve the housing system but unless they're willing to move away from the current ward system, they should be enforcing the one house rule for every character or FC, including retroactive application onto the existing ruleset.
The size of the player base has grown at a much faster rate than the total number of available plots even with the addition of an entirely new housing area. Combine that with legacy scenarios of individuals or FCs owning multiple plots, and there's clearly not enough for everyone. Even with retroactive application there wouldn't be enough but at least it would provide more opportunities for the newer players to land a proper housing plot (Harry Potter cupboard apartments or FC rooms don't count unless those get proper improvements as well). There's an FC on Chaos DC that owns 59 of 60 plots in a single housing ward which is entirely unnecessary. I know it, you know it, everyone knows it.
Realistically I'd like to see this:
- One personal plot per DC per game license
- One house-owning FC per DC per game license
- 30 or 60 auto demolition timer that's only skipped for the first occurance after an expansion launches
- Improvements to apartments/FC rooms so there's a second room and a balcony/greenhouse for planting onions
- Improvements to customisation options for placing objects so less/no glitching is required
- To follow on from above, a specific customisation option to remove those interior pillars on the walls
