Respectfully, consider that other people are actual people, and their lives are meaningfully distinct from yours. To wit, “climbing equipment” encompasses everything from the backpack of gym-climbing gear you describe to a half-ton of tents, rope, crashpads, anchors, packs, portaledges, outerwear, camp gear, etc.
Well, you also need quickdraws and anchor gear if lead climbing outdoors, and this doesn't remotely start to touch on trad gear, but you can set yourself up nicely for climbing for about $500.
The person you replied to does not have anywhere near $14k of climbing gear unless they are into serious big-wall climbing that involves sleeping on the side of the wall, or else they run a rock climbing guide company.
Edit: Just saw they actually listed their kit out in another comment, which tracks closely with what I expected. They could probably replace all of it for under $5k.
A full set of say a dozen cams, probably $1000. A set of tricams ($100). A couple sets of good nuts (2x$150). A set of hexes ($150). About a hundred oval crabs (100x$15) and a few beefy lockers (6x50$). Say 24ish quickdraws (24x$30). A half dozen belay devices/eights for various tasks (6x30$). Ropes are about 200 each for 50-60m dynamics. Any serious climber will own four or more. Plus some static lines for hauling. A set of jummars (2x150$). Lots of webbing for connecting stuff. A few thinner ropes for anchors and general utility uses. A couple pulley blocks (2x100). Rope bags. Gear bags. Cleaning tools. And a hundred other bits and bobs. Every wall climber also has an assortment of strange stuff, things few people ever see two of, for particular problems. For instance I have an ascender rated to catch falls, which is a useful self-rescue device. Such rare things are priceless.
Tricams are still sold. They are great in horizontal or shallow cracks. They are also way cheaper than mechanical cams. Hexes are still sold under different names (DMM Torque-nuts are just small hexes imho.)
100 seems like way too many, but things add up fast. Each piece of pro will need one or two. A basic trad anchor setup (three bit of pro) will involve five carabiners (3x plus two to tie off, and maybe a sixth if you want to top-rope the belay). So if you have a long pitch with say 15 bit of pro, and an anchor on either end, you are easily talking about 30+ carabiners in use on a single pitch. But you won't use every bit of pro on every pitch. You will have maybe a dozen other bits hanging off of you. That's another 20+ carabiners. So, on a single not-complicated trad route (no bolts) 50+ carabiners is not unusual. Get into complex things like multiple ropes and owning 100+ is not unusual.
Now having them all be ovals is strange. I took a stance early on that I wanted to standardize as much as possible. I bought BD ovals in bulk over a few years in the early 2000s. I like them, at least for everything other than quickdraw ends, rather than the random assortment many climbers end up collecting bit by bit.
It’s a fair fraction, on one hobby’s worth of stuff, nevermind the rest of the household (member’s!) items.
$14k just doesn’t cover replacing a household’s worth of stuff. If you still think it does, do a replacement value inventory of your place. And then update your insurance!
On the order of a few hundred per at most, but if you're climbing outdoors you probably will need a lot more than just those. Trad gear in particular can add up quite quickly.
In addition, it's not uncommon for dedicated climbers to have multiple sets of ropes/shoes (and even harnesses) for different situations.
When I took climbing, as a teenager, our instructor was very serious about getting the best stuff: shoes, ropes, crampons, carabiners, gloves, jackets, etc.
Not cheap, but he put it as “do you want to die?”.
Crampons are definitely mountaineering/winter hiking gear which I used to do a fair bit of. (For lower-grade winter hiking, various silicon spikes plus single-layer boots are pretty popular even among relative serious hikers up to some level.) Not rock climbing, which I always sort of hated :-)
But, yeah, even a decent collection of 4-season hiking/backpacking/camping gear--even if you exclude the previous gen stuff you don't really use any longer can easily get into the thousands of dollars though people do scrape by with consignment and the like.
But, by the way, that's one of the issues. In the natural course of things, you can pick up relative bargains over time, If you're presented with "repopulate your house in the next few weeks" not so much.
In fact, I'm presented with the latter in the next month or so. Will have to rebuy a bunch of kitchen stuff in particular fairly quickly and I'll probably just place some big orders with Amazon, Sur La Table, and a handful of other companies without doing much in the way of careful shopping other than pulling from various lists.
Yeah, true replacement cost is often well above "retail" because of the time factor. And hiking is one of those sports where you end up with a lot of stuff duplicated in bigger/smaller and/or warmer/cooler.
I never went out to buy a hiking outfit/collection after a class or whatever at a store. Had I, I'm sure it would have been more expensive and ultimately sub-optimal relative to what I own.
I'm talking about things like jackets of various weights, packs of various sizes. I have both medium (for wearing alone) and large (for when I'm wearing layers) jackets. I have gloves in various warmth levels.
Treat it more generally--gear that you are in some fashion going to trust your life to. It doesn't even need to be something fancy--a couple of days ago I was out on a hike and realized a companion was wearing jeans. The terrain was slightly scrambly (nothing that required any skill) and in a canyon that should have had a stream at this time of year. Fall into that in jeans and hypothermia becomes a very real issue.
Figure $3k or so for a complete set of gear to get you up almost anything in the continental US. Of course you can buy more or less depending on your goals.
How much does a harness, shoes and some rope cost?
