The problem with sticky notes isn't that you have a physical note with your password - it's that the main benefits of a password manager are a) giving you long, complex passwords that can't be guessed, b) giving you different passwords for every service to protect from leaks, and sticky notes are terrible at doing that at any scale, especially when you can't autofill them to the appropriate website.

Granted, a lot of services basically design their service for the common denominator of people using sticky notes by instituting rate limits, requiring 2FA, etc.
