I really don't think it should. Human rights should be available in all countries, but the world isn't free real estate at the mercy of enterprising individuals. End of story. The tribalism you're mentioning is just anthropology. With a good dose of rule of law it works well enough, and it does so at scale. If it doesn't work for you, well, tough luck. One thing that should be mentioned is that rights can only practically exist within confines that allow for their protection and execution. Something like a State or a culture, with defined boundaries...
