Yuppies: Young, healthy, fit people with enough disposable income and time to explore new sports on a whim, rather doing so out of dedication. Thereby increasing the number of people at the crags who don't take the sport seriously, and pose a danger to themselves and others. Not to say there aren't stupid poor people too, there's just less of them with $1000+ worth of gear.
That would indicate to me they'd be more likely to use good judgement in such an activity than someone at the crags who's never so much as taken a belay test. But they still regulate helmet usage on motorcycles. So your point is....
could not have said it better myself
