Look, if some authority finds your personal information on some server, and they can't produce your digital signature on a contract which says that the company can keep the information from some date to some other date, then they are in violation. It is simply not possible to lie about it.

Why does there need to be only one public key per user?

The authorities only have to look at the leaked information, contact you, and ask you to generate proof that you signed the contract.
