This is what the current government does but in the post-apocalyptic world it'll be less fair and more expensive.
The reason why government exists is because it solves very real problems. If there is state failure, we're not going to devolve into a libertarian utopia. What is more likely to happen is what has already happened in countries such as Somalia or the Democratic Republic of the Congo or Western Europe after the fall of the Roman Empire.
