For me also, and for camping, it's not just for disconnection from work, etc.

There's a very different psychology when you're completely self-reliant, with no communication with civilization. It's hard to express precisely, but it's powerfully liberating and a much more immersive alternative from everyday civilization. The door is shut on other options for a few days, at least.

(Yes, there's risk - though that can be greatly overemphasized and there's risk in everything - and you need to rely on yourself (and your group) to mitigate those risks and respond effectively to them, not on others. One leading trainer I read said that, once you're out of harm's way, the first thing is think. Nothing is going to happen immediately; the ambulance isn't going to be there in 5 minutes; the doctors won't see you for days, at least.)

The risk isn't the focus. It's just you and world around you.

Not everyone can do that - they have responsibilities they can't turn off, they have health challenges, they may want a compromise, like one of those emergency pager devices. I'm saying the effect of actually being disconnected is real, powerful, and valuable.
