This is all based on the premise that you maintain ownership of the DNS. Once you lose control of your domain due to legal issues in the relevant country, those references/citations become invalid. However, this is still a great improvement over the current situation.
My sibling links a great post on this, but to say it in a slightly shorter way, the core of identity is a DID, not a domain. You can update the domain associated with your DID if you lose control of the DNS and it will all transparently update.
I’ve skirted around this in the post to keep conceptual clarity but you can always move away from the domain (as a handle) without breaking links. This is because there’s a more persistent identifier that represents your identity (or at least there’s an option of having one, and that’s the default mechanism). Links between records actually use that identifier instead of the domain handle.
