I think for me, I'd prioritise lightweight. Nobody has ever gone on a hike and thought 'the only thing that spoilt that was it could have been a few grams heavier', but plenty have thought the reverse - and lighter kit is a safety thing too, you can walk further, you're less tired, or you can just carry more stuff giving you more options in a crisis (no more 'i guess i'll leave the first aid kit out').
wrt bulletproof, the question would be: how often do you do the kinds of hikes where you're getting shot at

I think most campers don't use their kit all that often, and regular campers are rarely using it in life-or-death situations - so durability and the risks of kit failure aren't big priorities.
If this kit fails, what is the worst that can possibly happen...? And usually the answer is pretty modest. I guess shoes are the exception to that.
Plus it's bushcraft - DIY and survival is part of the skillset, if you're into that side of it, kit failure can be kinda fun. Because it feels great to have that knowledge or problem-solving mindset to get out of a jam.
I do think everyone should 'invest' in stuff when they buy it, buy things to last - I loathe the people who leave their cheap quality tents in the woods because they're too much effort to take down for the cost. For ethical reasons, I always try to 'save up' over buying something cheap for expediency (or go second hand, and learn to fix stuff).
But 'guaranteed to never fail' is not where I'd put my money, if it was between that and weight.
