I carry similar gear as you do. Heavy parka is my last line of defense. I do carry storm proof matches though. I've never carried a bag or a stove, I actually don't carry a pad either to be honest. [...] I've been hiking over 40 years, many years never missing a week and I'm still here, so my system is adequate.
I am afraid you are following a logical fallacy. Your "system" (or lack thereof) is completely inadequate; it's just you have never needed to use it. Your reasoning is like someone saying her vehicle does not need seatbelts because she has never been in an accident.
