Why ban something like this?
People love what they are doing, or else they wouldn't try to climb the largest mountain in the world. Sure there are risks involved, but there is a risk in every day life. We have the same chance of dying in front of our computers as they have climbing. Smokers, bad drivers, drunk drivers, stupid kids running across the street when there is a lot of traffic. I'm pretty sure that not a lot of people die from mountain climbing, well not as many as car drivers.
