Here's the thing people need to realize: your email address, phone number, and any other digital identifier can be stripped and taken from you by whoever owns the service at any time. It doesn't matter if you host your own domain/mailer daemon, the host and/or registrar can choose to suspend your account as well. So really, there is no solution. Other than the realization that our communications channels are not ours, they are always someone else's, and we are forever at their mercy.

The PGP trust graph is the ultimate fallback here. As long as your public key is out there you can even not have DNS and change your IP address and still be able to prove the identity.

Self-custody has risks too, most notably theft or loss of the private key. It's tradeoffs all the way down.
