The easy and obvious answer is my love for the implied history individuals attach to objects. Culturally, we still flock to reliquary reverences and as individuals we cling to objects as a means to be close to past memories or future aspirations. Singular objects allow for viewer identity to be filled in as little or as much as viewers desire.
Importance is not that viewers share my thoughts or memories. Importance is that they recall their own. The simulated objects are the conduit or spark for that.
