I agree with you in principle. And my day hikes are not UL. But, I just rolled over to 47 YO. And my back and knees, both now injured (been hit by cars and snowboarded into some rocks), can't take the weight like I used to. My wife was also hit by a stoned driver while biking and the rod in her leg and cognitive exhaustion limit her. She also can't regulate her temps anymore, so we almost always carry a 10 degree bag, even in 40 degree weather. Lighter packs, bags and tent enable us to keep going. Hike your own hike, for us, it's worth some $$ to lighten up.
