Don’t most people that this this “correctly” use a password manager which stores passwords on the same device as stores the totp token and generates the one time code? Doesn’t this effectively turn your password into a device that you have, effectively turning the first factor (something you know) into something you have, while the second factor (something you have) is the same thing you have from the first factor (your phone)?
Even people that do this incorrectly and reuse passwords, probably also store their passwords in their browser, which is on the same device as their authenticator app. So I would guess by far majority of people are only using something they have twice.
