What part of Robinson Crusoe best demonstrates how is materialistic?

The part of Robinson Crusoe that best demonstrates how he is materialistic is when he lists all of the things he salvaged from the ship. He spends a great deal of time and effort salvaging the ship, even though he is the only person on the island and has no use for most of the things he salvages. This shows that he is very attached to material things and values them more than he values his own survival.
