I think the lesson of his ordeal is that you don't need to drag around a bunch of cutlery when in the outdoors. What would "two top quality fixed lades, one or two top quality folders, and a multitool" accomplish that his one multitool did not achieve? - what would all those knives weigh? What would they cost? That money and weight could clearly have been invested in items that would have been of more use to him. Actually, simply making sure that his route and plans were made clear to someone else, an action with essentially no cost, was clearly the best course. Being unburdened with unnecessary redundant gear is often a safety measure, and a wise decision, in its own way. Good judgement is more important that lots of gear, and your mind (making those good decisions, of course) is the most important gear of all.
"cheating death again and again" often results in failure to cheat death eventually, frequently in a way in which it doesn't matter how many knives you carry. If that lifestyle is your choice, that's OK - in a properly conducted society you should have that choice. Just be aware of the potential downside and accept the results of your decisions.
