I agree with you except that weight training/exercise has not only been shown to be safe, but also healthy in kids with normal health and development. There are extremes for sure, but the old adage that weight lifting will hurt you if you’re too young hasn’t held up to current research on the topic.

Proper weight training won’t hurt. But I got (and a lot of kids into sports/athletics get) hernia(s) because teenage hormones and physical reality are often at odds.

That may well be. I was trying to illustrate the broad range of activities in which we accept some risk to children, and may have been ambitious beyond my knowledge.
