Right, futures should be illegal, so people cant do things like hedge future exposure against adverse events? Farmers cant lock in prices at the beginning of the season - airlines can't lock in fuel prices as a hedge against rising prices, etc, etc.
Futures have a great many useful and very legitimate trading scenarios - traders who just gamble without hedges are not going to survive for long.
In my prior statement, I was referring to investors, who buy a stock, hoping it will rise on the long term, so I do admit my poor choice of words distorted my meaning somewhat, but otherwise I couldn't disagree more with your other statements
