The problem is that speculators are what keep the markets efficient. They take the risk of great swings in the price, hoping to make a profit. The people who need to buy or sell at a known price or secure a long term supply need these people to keep the markets moving. Sometimes that drives prices too high or too low for a short time, creating an anomoly in the market, but the underlying law of supply and demand always brings things back in line with the fundamentals.
