Sure, don't then. But other people are insistent that they can't tolerate the inconvenience of needing to own more than one authenticator, and yet they also can't tolerate the risk of losing an authenticator, so this is how they can square that circle.
My point was more that WebAuthn is starting to become a more viable option for the average person, with phone based authenticators that can be used to authenticate on multiple devices and keeps your keys backed up. I wouldn't use Google sync for WebAuthn myself either.
