Interesting.

I think that is it far more efficient and effective to travel light and get used to getting by with minimal amounts of gear. Hard experience has shown that historically survival kits are easily lost. Usually this happens at the worse possible time. At sea in the middle of a storm, thrown overboard into severe rapids, after you tumble down the side of a mountain, your likely to find pockets ripped off, kits lost, gear you had counted upon, gone.

As much comfort as you may get from a nice comprehensive kit there is a good chance when you need it it won't be there. So while I don't eschew carrying a simple survival kit I think it best to be fully prepared to make do with the clothes on your back, a knife and a source of fire. And to have backup plans of making do with less than that.
