Nobody is saying you have to......but if we did away with the function of speculating, it will have terrible ramifications for the economy.
Right, and thats exactly what I called for when I said:
"Oh please. Speculators are only interested in making money, which is fine. However, making them sound like some noble business person providing a valuable public service is extremely dishonest."
Which is why you chose to call me out on my bashing of the evil oil speculators.
Oh, and if speculators were to stop speculating, the economy would not tank. Producers would still produce and consumers would still consume - there would be more seasonal fluctuation perhaps - but the world would still keep spinning.
