I think i figured out why he wanted those things specifically. The people who showed him an item that was gifted/given to them, all had a personal and human connection to that item. A marriage ring, a lighter from a son, an item from a father, a pen that was a gift from parents. They all symbolize a connection to someone else, something the lawyer is obviously lacking. His friend showed him his item but the lawyer wasnt fixated on the item until his friend mentioned it was a gift from his father. So really, i dont think its the items specifically he wants but what they symbolize and stand for. human connections and a deep bond with someone else. Probably because he is a psychopath and cant feel these things he naturally is inclinced to want them and expresses in a materialistic way.
