A couple of items I would add:
Cellphone. If it’s a natural disaster you’re trying to survive, a cellphone can be a lifesaver.
I think you underestimate the value of cordage. Raise it in priority and recommend more feet of it.
Lighter. More reliable than strike anywhere matches and takes up a lot less space.
Snare Wire. Very useful in trapping food. Again, I’m thinking more of a natural disaster than an escape plan.
There’s a downside to carrying a cellphone - at least, one with the battery charged and in place: you can be found. Assuming he cellular network is still up, you might want to make a call when you first set out. After that, depending upon the circumstances, it could be a risk.
Recall that this load-out is intended for a three day )five, if you stretch it) on-foot E&E to get back home or to some other point of relative safety. An extended field stay is is another matter altogether.
