@Allegheny Tom, you sound like my wife.
And I don't mean that in a bad way.
I may have to chuck a bit in my pack. I do have several. But if I carried everything I "may" need, I'd have:
A handgun for packs of dogs and shady characters.
A full first aid kit with everything needed to treat broken bones, gunshots, stab wounds, etc.
An emergency GPS beacon. Some areas don't have phone signal.
A spare release. What if I drop one out of the tree?
Bow repair kit. What if my d loop comes undone?
Grunt call. What if he walks by and I have to live with knowing a grunt might have stopped him?
I could go on and on. Maybe it's being foolhardy, but I'm not carrying everything I may need once every time I go. That's how you end up spending all your time organizing gear instead of hunting. I'd have a 40lb back of junk I never used.
I need a weapon.
I need my boots.
I'm forced to carry a license.
Everything else gets viewed with suspicion. I enjoy the fun and freedom of hunting above everything else. My favorite hunts have usually started with a pocket full of shotgun shells and a desire to see something new.
Laying out and double checking my measly bit of gear the night before is already enough of a pain. If I had to perform a 57 point inspection every time I left the woods, I'd just quit going.
Two ways of looking at it. "It might, and then what?" vs "It probably won't, and if it does we'll figure it out."
Neither is right or wrong, I don't think. The gear that gives you piece of mind would just make me irritable. Now, if I was on a "big" hunt (like drawing for Florida sambaar deer) I'd probably be willing to carry a bit more. But I honestly don't know that I've ever lost an animal because I didn't have the right batarang in my utility belt.
