This was a great post. In fact, it may be one of the best posts I've read in a long time. These "rules" of S&D and turn certainly run the the game. The Japanese understand these rules very well - I believe Economics is a High School course for them.
As for stopping gil sellers - I don't think it possible to stop either Supply or Demand for this item, there are many options you could try that theoretically would bring the price down.
On the supply side, one, creating a new "company" that breaks the current price fix. An example would be players who band together and camp these items in the same fashion. This company would have to spend enormous resources to accomplish this though. And this company of players might have a difficult time not wanting to make more profit by going along with the price fix.
Two, kill the players - prevent the supply. This would also break the current price fix by killing the gilsellers, and allow players to get the items.
On the demand side. Either stop buying gil online, or stop buying sniper and archer rings. Both of these are also not realistic.
Don't like the 500K price tag? Your mind plays by economic rules on this as well. Is it worth the amount of time required for you to make 500K to buy these rings? If it takes you two weeks to make 500K, then pretend you are actually using that time to purchase the ring. Pretend you are a crafter, you can now actually make sniper rings, but this process takes you two weeks of hard work to produce one ring. Is this amount of time worth it?
On the other hand, lets say you can produce gil much faster. It only takes you a day to make 500K. IMO, A sniper ring is very easy to buy.
In these examples, you are playing by a supply production curve. I believe the two axis are time and quantity.
Let's look at one last example:
How long it takes you to farm 500K
vs.
The amount of time it would take you and some friends to get a drop off of stroper.
Which of these can you calculate to be quicker? IMO, camping stoper and competeing with the gilsellers is a faster way to get it. Then I would shout in Jeuno for a leather smither 90+ and ask him/her to make my sniper for a price. --You've just went around the whole system by producing the item your self.
But, I don't think many people do this, because 500K is a price some people will still pay. If people REALLY thought this price was too high, demand would fall, and so would the price.
Anyway - Really great post! Rate-ups!
Trolls - you are pathetic! Get an education! You are nothing but an example of a mob of people. Too stupid to understand and following everyone else. Damn sheep. And too afraid to voice your opinion - why? Because you KNOW you're stupid! Really irritates me.
