They really should just work on adding Private Rooms behind the Inns... I'd imagine the servers can actually handle it, though having SE actually chip in on the subject would certainly be ideal...
I mean, according to the patch notes (for 2.3), a single Estate can have up to 512 Private Rooms. There is potential for 1,440 plots per server. Now, perhaps the reason they mixed Private Housing in with Free Company Housing was to ensure that a number of plots cannot produce Private Rooms, giving them some wiggle room, but I do have to imagine that each server has potential for 737,280 Private Rooms. That's... A lot...
Again, actually having the developers chip in would be ideal here, but looking at the numbers available... That is simply the amount of Private Rooms that there is potential for, that is not a number that is likely ever to be reached... At best the game boasts what, having hit 5 million subscribers? Never mind the fact that they're not necessarily active subscribers, 5 million split across 64 servers is a measly 78,125 players per server on average... Even factoring in having multiple characters per account... Everyone would need to be rocking 9 characters, all of which they want to spend 300,000 Gil on having their own little room for, to be hitting the amount of Private Rooms there is potential for...
So, if there is potential for 737,280 Private Rooms per server, what is stopping the implementation of Private Rooms behind Inns? It shouldn't be too problematic to simply have the same option at the Inn that we have in Free Company Estates, to purchase a Private Room for 300,000 Gil, and then tie the Inn Private Room to the Free Company Private Room when applicable... Forget the wasted resources going into maintaining server space for non-customers, there is no chance in hell the potential for over 700,000 Private Rooms per server is being met, what reason is there not to implement that? Again, SE really needs to chime in here, because the only sensible explanation, and I suspect this to be the case, is that there isn't that potential for that many Private Rooms, despite their being potential for, per server, 1,440 Free Company Estates all with potential for 512 Private Rooms. I suspect that is exactly why Private Housing were thrown in with Free Company Housing, since a Private House does not allow for the Estate to produce up to 512 Private Rooms.
That's just a theory though, and despite owning property and being fine with this coming change, I'll remain fairly annoyed at the current state of Private Rooms based on these numbers, at least until SE drops by to actually explain the situation adequately. If anything that's what I'd be annoyed with here, the lack of communication from the developers about this stuff... I'd quite like to know how many Private Rooms they think they can handle, because slipping them in behind Inns is by far the best long term solution to Housing in this game. No it doesn't give everyone a Chocobo Stable (which I still recall as being something they're working on giving to everyone outside Housing), or Garden Plot, or Workshop, but it gives everyone their own little place to customize (which would be amazing for the fairly stagnant furniture market), and it gives everyone a use for those seasonal furnishings that are constantly being accumulated... The ideal is to turn Housing Wards not into a case of haves verses have-nots, but to just turn Housing Wards into a centralized location for the content it offers; I have my Private Room, Garden, Stable, etc., all in one place through Housing, where as someone without Housing still has all those things, just not in one spot. That's the best outcome I can imagine. Whether it's actually possible or not, we can only speculate, at least until SE decides to actually explain the situation...
