I'm over the initial shock of housing prices now. Once the gil sellers, titan mercs, and crafting/materia extortionists get rewarded with their giant mansion (a HUGE gil sink, and sorry if any of those terms seem insensitive to you, in all honesty), prices are almost guaranteed to come down. If you look at the patch notes from a broad perspective, you'll notice that they ARE informed of what is on topic in the forums and have listened to much of the feedback provided by us as players. The notes reflect many changes we've been asking for (as well as some to try and balance others).
My outlook for the future is that housing prices will take a drop about the time of the next patch. This is approximately the time the PS4 hits in Japan along with the beta for FFXIV. Forgive me for pulling out the "PS3 limitations" card, but I really believe that if even HALF the FCs on any given server were able to purchase a plot of land, it would create a lot of strain on the servers, and 10 year old console hardware. With everyone buying and customizing all this casual content at the same time, it may turn laggier than a HM Titan run.
I think this is a necessary evil to tease us with new, casual-type content, but it's also the most efficient at removing "dirty money" from the servers as well. It needs to be hyped for the server firsts to spend their gil in high amounts, but it also leaves a bad taste in the majority of players' mouths. But don't think that the prices won't come down soon, or that they don't listen to forum feedback; don't think that for a second. There are amends that must be made as being built on top of an existing game (1.0), but be assured that in a few months - perhaps after the next patch - this whole scandal will have blown over, and we'll all be much happier in the long run.
I'm not a "white knight" for the company. I just stopped and thought about the situation logically for a minute instead of letting my emotional response get the best of me. You're right that SE has data on each FC, as well as how much gil is in circulation across the server as a whole. These prices may seem outrageous to people like you and me, but just have a little faith that this is for the players benefit in the long term of things. It's a calculated move by Yoshi-P, but whether players decide to abandon the game like the first wipe of a dungeon run, or hang in until the end .......... Just try and play it out.
