viion your point is that you believe once the market stabilizes people will be paying more due to the re-denomination, is that right? So the counterpoint that "people won't pay higher prices" is moot, because they won't have a choice.

I guess I'm still thinking that people will buy what they can afford, and people will only sell what others can buy. Even if there wasn't going to be a re-denomination, item values would shift due to game changes, so your scenario has the potential to be true regardless. Just the same I think an influx of new players (which is inevitable at least for the short term), who all have 0gil to begin with, must have an impact on item prices. Rampant speculation doesn't really accomplish anything, as you've pointed out, but I also don't think there's any reason to worry too much one way or the other.

Ultimately there are far too many factors involved to say "we will lose money due to the re-denomination," especially since the denomination of a currency has no bearing on item cost (or, if any, far less than supply/demand). If prices go up, they would have gone up anyway, and likewise if they go down. This by itself is not a catalyst for a significant market shift in either direction, and even if it is a contributor there is an ever-growing list of things that will contribute far more to valuation of goods.

People don't like being taken advantage of. Those who have been around and know that prices are too high will refuse to buy. Those who don't pay attention... hell, if they have the gil then let them spend it. There's nothing stopping folks who are "losing money" from likewise making it through the same circumstances, as has been pointed out.
