Life is dangerous. Seriously, you can easily slip, fall, and die in your bathroom.
Statistics are how we determine how risky an activity is. Mountaineering and rock climbing are statistically safer than driving. Yes, driving is dangerous, but nobody says shit about not having compassion for those who die because they take a road trip.
All of those risks you mention associated with climbing exist, but you're dramatically overestimating how common they are
I ran the numbers per hour on mountaineering (related to rock climbing, but not exactly the same) and driving is more dangerous as of about 6 years ago (when I ran the numbers).
I believe the fatality rates on rock climbing are similar, but don't quote me on it.
The bottom line truth is, mountain recreation isn't nearly as dangerous as people think it is.
