No, there really aren't. Market Board fees, Teleport/Airship/Porter fees, and Repairing fees really are not enough to counteract the massive amounts of Gil players get from; FATEs, Levequests, Regular Quests, Dungeons, Duty Roulette, Hunt Marks, Treasure Maps, Clear Demimateria, Challenge Logs, and whatever else I'm forgetting.
The amount of Gil I get per day is astronomical, even compared to the amount of Gil I lose in fees per month. Every week I'm walking around with an extra 100k at least, just from playing the game; that isn't Gil I got from other players, it is literally Gil the game has just given me for playing, and there is literally no Gil sink taking a significant amount of that Gil out of the system. Not every player is going to be making that kind of Gil a week, because not everyone plays the game the same way (some don't touch the Duty Roulette, for example), but we can assume that a significant proportion of players can and will. That is a lot of Gil being printed per server, with a pathetic fraction being removed.
Reducing the cost of Housing pleases everyone.
Adding a tax keeps it as a Gil sink long after you've payed for it.
That reduces the ridiculous amounts of Gil being printed, and goes a way to fixing the hyper inflation that even lead to them making housing this expensive in the first place. Housing was designed to take Gil out of the system, that's why Legacy servers are burdened with ridiculously higher costs. The current system for Housing doesn't do that in the long run, and the massive prices have obviously just been upsetting the player base, even as far back as 2.1. Taxes solve that, as long as they balance it so it isn't ridiculous, it would work very well.
The only remaining issue is accommodating space for everyone to have a House. Having both instanced and non-instanced Wards should solve that; they're certainly not going to solve it with their brute force approach of doubling the number of Wards. They wasted nine months doing absolutely nothing but giving everyone access to the exact same thing we had in 2.1 when they should have been working on any number of things really. It's really quite sad, I wont say Yoshida should resign, but whoever was actually in charge of Housing certainly should. What we got in 2.38 could easily have been in 2.1, you do not do that kind of work and expect to keep your job. When we didn't get Personal Housing in 2.1, it was under the pretense that they were working on it, when it kept getting delayed, it was because they were working on it. I'd really like to know what they were working on, because it looks like absolutely nothing.
Heck, even if they don't want to make a constant and effective Gil sink, they can just give you the option to pay up front or pay over time. The main issue here is that they also want to use the cost to halt demand, hence why the prices depreciate, which is a serious mistake. If they wanted to halt demand there were plenty of ways of doing so, they were just too lazy to bother with any. At least when 2.1 hit FCs needed to grind a few ranks to even purchase a House, they couldn't even be bothered with something like that here. It's just incredibly lazy. They should have spent the past nine months addressing the reason why they even need to halt demand.
