> You still needs a way to prove that you are you - with legal protection and recourse. You actually have something that you can use- your reputation. It is difficult to fake your likeness, even moreso to people who actually know you. A combination of past preshared secrets (memories) alongside your likeness is enough to get people who DO have ID to vouch for your identity- family, your landlord, your neighbor, your lawyer, your employer, past schoolteacher, anyone who can reasonably be expected to recognize you and have had some experiences with you, can discern whether or not you are who you say you are. From there you could have access to your theoretical USPS or Library email, add an additional PGP key to publicly-funded keyservers, and generally use the power of this vouch to escalate from there. Even if you make an extreme edge-case argument, saying that someone has some extreme amnesia and finds themselves far away from their home, the government could just let you generate a completely new identity for a small fee, so that you aren't left high and dry without one.
