For every rich ally that you get to do this (let's call you disruptionists), there will be 10 speculators watching the markets, attempting to keep the prices steady. You might be able to get black dye down to 2k if you flooded the market, but it would only stay that way for about 5-10 minutes. People like me are constantly checking prices. If I find black dye at 2k, I'll start buying as fast as I can until I either:
A) I run out of cash,
or
B) the price reaches 3200.
Likewise, I have very large stashes of silk and scales in my bank. In the past, I've had large quantities of parchment, steel, or leather. In any case, these stashes have just been sitting there, waiting for the market to spike. I acquired them from the NPC trader some time back, when the price was abnormally low. Once that market does spike, I'll finally sell them off and make a profit. It should be no surprise to you that there are hundreds of other players just like me, who watch the NPC traders closely, hoping to skim a few dimes off here and there.
So, the day you and your disruptionist friends buy lots of silk, I, and all of my hidden speculator "friends" out there will sell our silk, to equalize out your disruption. (Personally, I really hope this happens
) So, you'll be stuck with a large amount of silk in your bank, but you'll have bought it at normal market prices (in contrast to me, who bought at extremely low prices Sunday morning, 6/19 at 7:15 am)No matter how you look at it, you lose.

I remember hearing a story about someone who tried to corner the silver market. Basically, he bought and bought until there was a national shortage. Then he slowly sold it back, to make a profit. This would be impossible to do in Guild Wars, because most of the trading is done player to player, not through the NPCs. So, there is no way to completely corner a given market.
