I doubt Larian cares about multiplayer design when all their games are resoundingly played as majority single player campaigns. It could be as simple as wanting for items in the world to have their use. If scrolls are too powerful, they can simply make them more scarce and expensive. Healing from food makes sense, though it should only be out of combat healing, or maybe change food so they're ingredients you can take to camp on a long rest and use on the bonfire to apply party buffs until the next long rest.
