You can also use some spells to turn them into projectiles if you want to! Besides, in actual pen and paper dnd you can pick up pretty much anything if you want to, why not in bg3 too. Some players will get some use of them, whether it is some weird combat use or just to decorate their camp.
I got nothing against the clutter per se. I'm just curious if there is something I should hold on to in case i have need for it later on. Rope for climbing, hamers for crafting and so on.
