Free, libre, open source software, peer to peer networks, and citizen run communications infrastructure are the only viable way forward if we don't to live in a rental society where none of your belongings belong to you, not even your identity.

Which is a touch more solid (I use in in that way) but still an ephemeral rented thing, not owned.
Ultimately, you're going to depend on other parties behaving in a common interest, whether that's your email provider, your ISP, your registrar, anyone accepting your ip address announcements...
They can take my email address, I'm keeping my emails.
Got a mail client running on several machines for that reason. All hail IMAP.
Notifying all the people I've ever sent an email to of a new address is a quick task with an offline email client.
Changing the email address on all the accounts is a bit of a chore, but that goes with (as you rightfully say) not owning that email address.
Guess one of these days I'll run a mail server just for creating online accounts. It won't even need to send anything, so no worrying about aggressive spam filters. And it can auto-delete everything each day too without harm.
