Yes, send to camp is useful and is hard to ignore (the game is balanced around its existence). But that is only because it is a fix for another problem: there is too much loot.
Well that’s a whole other debate that again comes up again and again on these forums (see eg
https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=843143).
Personally, I do think that improvements could be made to looting, but disagree that there’s too much loot overall (though I’d agree there are too many potions, for example) or that the game is balanced around sending to camp. I wouldn’t pick up everything not nailed down in real life, and don’t in BG3 either. Personally, I find it immersive that there’s more stuff in the world than just items obviously created for me as the player to use or interact with, and think the game is more fun and interesting from a resource management perspective if I don’t loot too much and, by and large, stick with what I can carry within my weight allowance.
If others prefer to loot absolutely everything, then that’s of course their choice, and I can see Send to Camp becomes more of a necessity. But I’d argue that once someone has decided to take that hoarder approach they’ve already decided realism isn’t a priority for them, and I wouldn’t expect Larian to make their unrealistic behaviour have realistic consequences if that would negatively impact other users who are using the QoL features more selectively.
