Not to sound terse, but to hit the points I noticed:
Swap the Light my Fire (4 oz) for a SAK Classic (21 grams and you can butcher a bear with one)
First Aid kits can be 2 ounces.
They’re a little hard to find, but carry a 1-ounce DEET, not the 2-ounce.  At least don’t bring it full.
Not a small roll of duct but just 8 or 16 inches wrapped around your water bottle.
BRS-3000T stove is 25 grams and $11.
“Lighters” but quantity = 1? Bring two mini-Bics, in separate compartments. 11 grams each.
Got tent stakes? Including guy lines?
Petzl’s e-lite is 0.95 ounces instead of 4 ounces. Or the super-capable Zebralight SC52 at 1.4 ounces. Having the head strap is only handy in camp. On the trail, the light should be at your waist so you can see dips and bumps in the trail.
Those boots have to go. Weight on your feet is picked up, accelerated, de-accelerated and put down again, 100 times a minute. There are a lot of light-weight low-cut hikers. And those boots don’t protect your ankles from twisting, only from getting bumped. To protect your ankles from a sprain or a break, they’d have to immobilize your ankles, like a downhill ski boot does. Then you couldn’t hike.  And leather boots take forever to dry.
If your food doesn’t have water in it, has some fat, and minimal packaging, 1.5 pounds/day is a good target. Unless you’re putting up huge mileage AND you’re super lean already. Pity to carry out extra food. Being 500 calories low each day won’t kill you – dropping 1 or 2 pounds of body fat on a week-long trip would be a benefit for most of us.
Amazon says that camera weighs 0.76 pounds, not 2 pounds. Much less of a boat anchor. Multi-purpose your pillow or hat or something into a padded camera case.
