There is no "artificial" but only a "temporary." As you said, in regards to OPEC, when the price of oil gets to a certain point it "beneficially works to encourage the development of energy alternatives." That's because OPEC doesn't control all the oil. In a market like gum you get X amount of players producing Y amount of gum. If a bunch of players form a cartel to capture the gum market it only encourages others to produce more gum. Yes, in the mean time the cartel will benefit, and in an emerging commodity where they are big enough to do so they might make a huge profit. But they have to be offering their 0 star trades for something, right? So the something for which they offer 0 star trade has it's demand go up and any doing well and reading the market will produce that something and undercut their price until the whole thing gets down to the aggregate value of gum to those trading for it.
On a similar note. I noticed a steel shortage and a scrolls shortage. I choose to put out 14 very large steel mfrs and now I have 5 million steel -- I was up to 10 -- which I trade for scrolls and everything else. All my goods hover around 2-3 million and I clear the trade board in my neighborhood about twice a day. I sell only 3 star trades exactly because I have a huge surplus. If you think about it, I'm just reflecting what steel is worth to me and trading for it at what I consider a "fair" value.
The most efficient response to the behaviors you describe is to produce whatever they are trying to corner and undercut their prices. It's only "artificial" until the market forces kick in and the supply goes way up.
And finally, I suspect it's pretty hopeless, but if people just quit taking those trades the players wouldn't keep putting them up.
And, yes, you could slow down. Part of being first or at the forefront of the parade is if there's a wrong turn in the parade route, you will be the first to take it...and end up in back parking lot of you local (closed) K-mart.
