Rarity is also used to generate random loot, and to determine how difficult items are to identify. There are amounts of gold in the list, but they obviously don't require lore/intelligence to identify. Both rarity 1 and 0 are automatically identified, but 0 is for items that never appear in random loot.
There are also some repeats of names, like "Armor" and "Boots". These are actually different items with different attributes (armor rating, damage, etc.) and the same name. And some, like lockpicks, actually appear at multiple rarities.
