“…Some everyday examples suggest that permission is not needed for helpful actions that violate the right of exclusion to a lesser degree. For example, you are allowed to bring lost items to a lost-and-found (e.g., Lastdrager, Montoya, Hartel, & Junger, 2013; West, 2003), to mail a letter you find on the ground (e.g., Milgram, Mann, & Harter, 1965), and to help retrieve objects that were accidently dropped (e.g., Guinote, Cotzia, Sandhu, & Siwa, 2015; Warneken, 2013). Unsolicited repairs violate the right of exclusion more flagrantly (i.e., they involve modifying property) and are not needed to ensure that property is restored to its owner.…”
