You missed the point.
As an adult responsible for kids shooting off model rockets would I take all precautions? Obviously. Not only because it's the duty of the older to set an example for the younger but because our litigious society would take my house away if I didn't. But would I draw conclusions from observing others taking these precautions that model rocketry is so dangerous that no way on Earth should anyone do it without taking precautions? Ah, no. You can't bubble-wrap the world and people need to understand what risk is all about. Risk should never be used to frighten people away from taking risks. Electric ignitors today are safer than the old-school way of setting off rockets which was to insert a fuse into the butt end of the rocket and light it off. But only marginally.

And not every kid who does survive does so without losing or damaging some parts. Any EMT, Paramedic, or ER staff can tell you countless tales from the other side of that probability curve. But those are best shared in-person over some frosty beverages, not on this list.
