If I was to imagine what I didn't know about mountaineering, it might be about working to see views that I couldn't have imagined.

To be clear, I think mountaineering is a perfectly rational activity for people to pursue so long as they're going into it with their eyes wide open. I've certainly done activities in that vein that some reasonable percentage of people would probably consider excessively dangerous for various reasons.
I wouldn't personally do many of them but I'd hesitate to criticize people in general for pursuing activities that have greater than typical day-to-day danger associated with them.
It's essentially impossible to properly normalise across hours of doing the activity.
Those stats, are at best, an estimate but it's exceptionally favourable to mountaineering.
However, as both you and the link suggest, it's essentially impossible to normalize. I don't know how I'd even draw a hard line between a "walk in the woods" and "mountaineering." But do whatever works for you.
I do (and love) outdoor climbing and even a bit of mountaineering, but it seems like most accomplished climbers die in the alpine. Some of what people do makes Honnold's famous free solo of El Cap look tame by comparison
But people like challenges, experiences, etc. some of which are never going to be wholly risk free. I'm not going to pressure someone to get out of their comfort zone in a way that puts them in potential physical danger but I fully understand people who pressure themselves. I've certainly gotten into some dicey situations now and then. Nothing serious happened--I was generally prepared--but it wouldn't have taken a lot for things to go sideways.
Or maybe you get distracted and forget to look both ways before crossing the street.
Its the same with mountaineering.
