Do gingerbread people feel weird about living in gingerbread houses, that their house is made of the same material as their flesh, or in gingerbread world, is the material only the same on an atomic level, like how humans are made of carbon and so are most building materials?
Gingerbread people are bestowed life by magical bakers. The same magic could be used to bring a gingerbread house to life it just would be in a nightmarish situation since houses don't have many moving parts besides doors and shutters. Most magical bakers would never do something like that because magical bakers are bestowed their powers by the love of the people they feed. People who find joy in feeding others are rarely ever evil and therefore would never create a nightmarish monster gingerbread house.
