I realize in many ways we are just arguing about semantics. The reality is we take risks. The key is to understand the risks so you can accurately evaluate whether you are comfortable with that level of risk.
to add to what neni says, it can be hard to carry everything you want to or that you should carry. My pack is only so large and it already feels quite heavy. Speed is safety in the mountains and being able to travel fast and light without getting exhausted is important.
BC is all about risk management, and the gear you pack is part of it. The more you pack, for the more situations you are prepared, sure, BUT the heavier the pack, the slower you get, which in turns increases your risk. It's give and take.
Thus it depends on what type of BC venture is on the table that day. Like, if I would pack for a multiday traverse in a rural place with no cell coverage and rescue? Sure, my pack would be totally different. But so would be the plan for which route and how far. (Since I endure cold badly, this is out of my scope anyway. I only do multiday hut to hut trips. I.e. only basic survival stuff needed to increase my personal risk feel as I reach a warm hut in the evening). Different bc trips require different gear and allow for different travel speed and routing.
OTOH, there's an absolute minimum which I take to venture BC. Beacon, probe, shovel is absolutely mandatory to me even if it's only lift accessible resort peaks towering above lifts n groomers (which at ours is bc cos it's not bombed nor patrolled). Just today, it was incredibly tempting, as someone did one of those peaks and it looked as if there is real nice pow, and it means this someone has cut the necessary steps... would have been an easy 1hr bootpack from the top lift to access a great 800m run back down to resort. Avy risk down to mellow. Tempting. But we didn't have any gear, so it was a clear NO.
I know ppl who do that peak in such conditions without any gear, solo. And that's fine. That's their personal risk level. It's not mine. I always think that I don't want to end up as that gal in the statistics who would have an avy pack n allat home
but got caught that one day she rode in resort mode with nothing.
Same goes for many other, slightly less risky "bc" off piste runs at ours. Countless ppl ride them without any gear. I don't. Because shit could
happen. Has. Risk is low, but the remaining odds are too high for me. Not high enough to keep me from riding there, of course, but... IF shit happens, I want to be able to search my partner, do everything possible to find him and keep him alive. Sure, there'd be the risk he died from trauma anyway, or I wouldn't reach him quick enough, but those are the margins we take and live with. What I couldn't live with is standing there bare handed, not able to even try to rescue him because we went without any gear.
So... in short: bc <> bc and risk management is a personal thing.
