You are correct in saying that the virtual world is not free from hazards. However, the difference is in feedback and evolutionary development.
In the real world, you feel the snakebite or the hot stove burner. When approached by a stranger or walking through an unknown neighborhood, thousands of years of predator-prey evolution gives you the feeling that something is wrong and you should flee.
We haven't evolved these levels of intuition for the virtual world. I can open a harmless looking email and infect my home network with a virus and never know it happened. I can't reliably tell if the person I'm chatting with is a predator or a friend.
