I think perhaps if I (and others) approach this from a very personal (not intimate
) point of view then it'll probably make more sense I guess.
I live in a city. I work obscenely close to home, so I have no EDC (other than dog doo bags which I always have
) I have no PSK...why do I need one? If the world falls in to the point where I can't get my stuff then I'll deal with it then, I also can't walk about work with a tool belt on...
So then next step, walking doggo locally... again, there is a lovely park that is a stones throw from work and home, so rather than load up a utility belt, or bag just simply to have a stretch of both mine and doggos legs, I simply grab the most useful tool (a mobile phone), doggo, lead, aforementioned doo bags, "bally" and maybe headphones and off I go, again home and gear is a 5 minute max sprint.
Out and about, so again, I'm never too far to walk home, supermarket I go to is an hour and a half walk if I broke down or was unable to drive back...and even then, I'd call a cab if I was desperate...
So then vehicle trips... again, 2 best tools, a charged mobile and my wallet... I'll normally have a bottle of water with me, invariably there will be some snacks somewhere inside... only additionals I have would be a small tool kit and tyre changing stuff, if I can't get out of a situation using those I'll call the AA or start walking.. oh and I have CPR masks and FAK in both vehicles.
Next? A day out, choices to make, van which is roughly insulated, has storage and a pull out bed in, lights etc and likely all the gear in the world I own can fit in it
... or AWD estate type car which has all season tyres... dependent on year and activity would depend on choice... Into the vehicle would go all my stuff which has back up bits and bobs for my activity of choice.
Next? an overnighter or longer, would be the same as previous paragraph just geared more to a longer stay.
Now having lived in the countryside, when I return to it in the future, I'll likely adapt things a bit more so that I carry a bit more either in my vehicle or on my person, but those are the reasons for me why I think it's a bit redundant.
