You can't abstract around how our brains are wired and they are wired in a way that wants to define ingroups and outgroups. Unification is a futile concept. Humans will just figure out how to create ingroups and outgroups based on a different basis. Maybe they'll use clothes branding, like back in high school. It would be better to go with decentralisation and fragmentation, so you have lots of small groups, but everyone from that small group would be part of the ingroup.
