I don’t disagree with the idea that you should stay put as long as possible - that’s also true of aircraft crashes, etc. The question though is if you were forced to what are the essentials you would take with you.

If you have to leave because civilization crashed, you will be dead in 72 hours since most people who would be on foot would use you as their BOB.
In non-TEOTWAWKI scenarios it is quite simple: .45 1911, burn phone, passport, pre-paid debit cards, and cash, cash, cash.
I agree with cripplecreek, stay put unless the house is literally burning down around you.
The whole idea of a BOB is actually ridiculous once one actually thinks about it. Moving solo on foot for a hundred miles? Really? Only in grade-B movie plots. If one is stupid enough to leave the house, it better be in a crowd of friendlies and be the one humping food, the Katadyn and the coffee. With that as barter, everything else comes easily.
One thing I have in EVERY vehicle and EVERY BO bag is fire means. Magnesium sticks with a flint and simple but high quality knives. I have them to the point of ridiculous. Grab any BO bag from a fanny back to major clutch in my CJ and they all have a way of making fire with no stick rubbing. In the outback if I step out of the vehicle a BO goes with me.
Based upon your list I will be adding snare wire to all kits. Slow and somewhat inefficient but still very handy. Do not forget a roll of 550 paracord. Very versatile stuff.
