Words of wisdom my friend.
I get enough of the minimalist thing when I am teaching it here s.e.wilderness.com But I also teach against an intentional minimalist approach other than training for an incident. As you said it's easy to test yourself...but still better to be prepared for contingencies that have a nasty habit of occurring.
If you've ever seen how full my backpack is, you'd think I was the most unlikely person to preach minimalism, however, more often than not, the backpack ends up stowed in my closet, while I bring my less bulky haversack. I'm a minimalist simply out of laziness, and ironically it's served me well. Like a person who's never seen a TV, I don't even miss all of the extra junk, (which is exactly what it is...junk). Beyond the 5 items mentioned above, what else do you really need? I've stomped around the boreal my whole life, disappearing for a month at a time with little more than a knife, a steel, a bedroll, the fly off of my tent in case it rains, and the first 24 hours worth of food.
If you don't have it, trust me, you won't miss it.
If you want to come out my neck of the woods, I can show you a lake in northern Ontario so full of rainbow trout, you can catch and dry enough, in one day to last you 2 weeks, the shoreline is peppered with wild raspberry, blueberries, and the surrounding forest is loaded with apple trees. It's a secret tho, so you'd have to come blindfolded. lol
