Um, you’re not really selling this. That’s a pretty low bar.
Mate I’m quite risk averse but come on, you ever leave your house or too dangerous?
Mmm, I take plenty of risks, but for a purpose beyond assuaging my boredom. Heck, I’ve been up in a work harness many times, on a ship at sea (200ft above a metal deck with the waves rocking you back and forth is… interesting).
Without a reason to go there, this is just entertainment… expensive, high-risk entertainment.
Someone else mentioned these are pro climbers. Your previous arguments that this is unnecessarily risky, that they are idiots that cannot plan a route etc have already been addressed by me and others. Now it turns out that you are acrually a cool kid that has a good reason to be high up in a harness but they don’t, they are just bored and looking for entertainment. Whatever mate, surely it’s them deserving the Darwin award here…
