Biometrics are not an extension of #2.
You really are categorizing authentication factors by their weaknesses:
- Knowledge factors can be discovered/guessed and duplicated
- Possession factors should protect against guessing and duplication, but can be physically stolen
- Inherence factors should protect against guessing, duplication and physical theft, but cannot be replaced
Writing down a password doesn't make it an effective physical factor, just like embedding an NFC chip in your arm doesn't make it an effective biometric.

The mapping of your phone number to your phone is not something you possess, it is sitting in some phone company system somewhere and it can be changed.
