That is a very optimistic approach and in a perfect world it would be a great thing to help everybody with giving them a talk about the consequences of their action and that their current path will likely lead to large financial losses. Unfortunately, we are not living in such a world, people are very reluctant to take advise from strangers and will probably not trust us, even if we are honest and only want to help. The difference between futures trading and gambling is the access to the two. Everybody who is 18 in my country can enter a casino and start gambling if they have the money, whereas starting to buy futures you need to setup a special account with the bank. I remember before being able to trade futures at my bank I had to fill out a questionnaire about my previous trading experience and my knowledge. Also, in a talk with the bank employee he showed me again that the losses from futures trading can be much higher than when trading stocks. So, there are special regulatory requirements for futures trading to protect people from themselves, in gambling such a thing doesn't exist. The problem is that futures trading usually involved leverage, which can lead to financial problems, in the casino we usually just gamble with our own money and if we lose it we have to stop. Having more protection for the customer is a good thing in futures trading, but in gambling there it’s not really necessary.
