.. and then you lose your 2FA-info or are blocked because Iran.

You need to lose your 2FA device, like your phone, the recovery codes (normally in a password manager), AND the local copy of your code at the same time.

Reality may be a bit more complex.

- You may not have all your source code repos synced locally. Maybe you think you do but forgot one.

- You may keep your phone in your computer bag and lose both at once (both your 2fa and your code).

- You may drop your phone in the ground and fail to get access to your password manager.

.. etc.

Having a backup strategy which involves you not breaking a piece of glass (aka phone) you play with while sitting on the toilet is a bit risky.
