 Finally, endurantists could adopt a restricted ontology, as some do in response to temporary coincidence. If there aren’t really any such things as bicycles, buildings or lakes, just particles moving around and interacting, then there are no issues to resolve about the careers and identities of bicycles, buildings or lakes. As before, the main difficulty here is in reconciling our everyday beliefs with a sufficiently restricted ontology: after all, people and even fundamental particles seem sometimes to be indeterminate. (Again, it is open to perdurantists to adopt a restricted ontology, but typically they do not.)
