If you can not swim you do not go to the sea, trading is the same, better go to the casino ..
Great analogy, but people love to do what they know they can't, you suggest them to go to the casino and casino games are also a fast way to lose your money and yet people have the illusion they are going to somehow beat the house in their own games when most people that have ever tried have failed to do it, so this extreme confidence in ourselves is a huge mistake when dealing with such strong opponents.
