I think people who are into crafts. They have all of these yarns, construction papers, various tools and stuff. All so that they can say that they have all of these projects in mind that they want to do. But they never do them so they get more crafting stuff and it just eats away storage until their place is practically consumed by it.
The ultralight stuff is a whole new set of gear I’ve considered buying but don’t know if I’ll use it enough to be worth it. My old school ass carries about 50lbs on a weekend trip though it drops fast as I eat up the food and drink the beer. I managed this for decades while my body weight was about 130lbs. Now I’m at 170 with plantar fasciitis, mild arthritis and possibly Covid lingering effects.
I’m not even ultralight. I have a framed pack and a whole toothbrush. Those guys are nuts.
