It’s looking pretty good. Ignoring the water you’re at 11 pounds base weight with admittedly more clothes plus the chair for chilling.
The biggest things I’d change are negated by your desire to hang out and enjoy the scenery and hence need somewhat more clothing. Still, I see a few ways to drop a pound or two:
A BRS-3000T (and lighter) is 1/3 the weight of that Pocket Rocket + lighter.
Cup + cozy at 3 ounces could be 1/4 of that. My 16-ounce polypropylene cup is 0.74 ounces and not so conductive I want a cozy around it. If you want a cozy, you have 6 socks along and can only wear 2 at once.
32 ounces is a LOT of carried water. Maybe that’s your worst case, but in the fairly wet place I am, I carry no water. When I get thirsty, I grab a liter at the next stream and zap it with my SteriPen. Any beta you can gather beforehand or get on the fly from GutHooks could save those two pounds. If you know there’s water 1-2 miles ahead, why carry any?
7 ounces is a lot of “cords and stakes”. Go really light on the stakes. In a pinch or a storm, you can bury a stick as a deadman anchor or tie out to trees and bushes. Cordage, however, is invaluable, but it doesn’t have to (and shouldn’t) be 550-paracord. My goto is 130-pound-test braided Dacron halibut fishing line. 25 feet = 6 grams. Available in various strengths on Amazon as fishing line or kite string or at Sportman’s Warehouse or any fishing shop by the foot.
I’d reduce the three pairs of socks to two and/or forego the gloves (socks can serve as gloves).
If you had a slightly bigger tarp (you already have a bug net), could you forgo the bivy? Maybe that’s the next big purchase?
The Cosmo headlamp isn’t wrong, but sometimes I’ll bring just a $10 10-gram Nitecore Tube which gives me 50 hours on low which is enough to hike an established trail or 2 hours on medium. Your phone is a back-up light. But you southerners actually get some night time in the summer.
6.3-ounce pillow? My Klymit Pillow X is 2.27 ounces. It’s not quite as much height as I want (no BPing pillow is), so I put clothes-not-worn in my quilt’s dry bag and put it on top of the pillow.
