I agree, this is not a very good use case for blockchain. For example, you can use a bank statement or utility bills to 'prove' your home address - It's not as solid a blockchain proof, but the courts will accept it... The fact that courts of law don't depend on blockchain-quality proofs means that blockchain does not actually solve any new problems in that area. It can add a bit of extra convenience in certain cases but the value is unclear.
