Have you ever wondered why trading onion futures has been banned since the 50s? You're saying the answer to the above question is "because there was an immediate problem with onion futures in the 50s". I don't think that's what they meant. That would be unrelated to "the fact that futures markets are so heavily regulated". I guess if everyone has a different opinion, and every reply comes from a different person, there's no "discussion" as I understand it.
