I don't think the designers of IPv4 claimed to be non-political. They were working on a project to link the US military with major US universities. I agree that IPv4 is also a poor basis for systems that are generic to all possible politics - I just don't think the designers of IPv4 ever made such a claim. I also think the politics of the designers of IPv4 are closer to the politics of most people on this forum than the politics of the designer of Urbit. So even if there are political assumptions encoded in the use cases it was designed for, they probably do match your use cases.
