right now if another copy of you comes by and claims your wife and your house, you'd be miffed. but the whole concept of one of you owning the house is just an artefact of how individuality and possessions happen to be right now. it doesn't have to be forever. there was a time you could steal a picture and have the only copy - now you can save a copy on your phone and you don't deprive another of theirs. some day people and stuff could behave the same.
