IIUC, you're arguing that "whole-town" level aggregation is misleading. So if we get more granular, we could do it my neighborhood, street, building, apartment/car/shelter, bedroom, bed, bed @ time of day, etc. Any one of those aggregation levels could hide interesting distinctions that could be made if only the data were reported with even more granularity. So are you arguing against aggregation in general? Or just whole-town aggregation specifically?
