Any concept of "strong security" that doesn't consider losing access to be a security issue is, at best, amateur.

If a state actor can't access your email, but you also can't access your email (and receive notices of login attempts, password reset attempts, server intrusions, etc.), then you absolutely do not have a good security posture.

It doesn't matter how you want to describe it, keeping recovery keys available is an ongoing maintenance burden that most people aren't going to do perfectly. It's not appropriate to blame users for reasonably foreseeable problems with a fragile system and lock them out of their bank passwords.
