By definition, homeless people don’t have homes. But an address is not a home. An address, today, is an identity; it’s a way for society to check that you are not just a person but the person you say you are. How many times have I been asked to show proof of address to register a child in school, to vote, to open a new account? It’s not for the bank manager to come and meet me at the door. In the modern world, in short, you are your address.
