Tell that to the people who have lost access to their Google account.

Now we aren't talking about a security problem, we're talking about who really owns what. Google can lock you out of your account no matter what kind of authentication they use for that account

It's a lot easier to be locked out with a passkey than without one.

No it's not. Google flips a bit in their database and no matter what kind of authentication you set up with them, you get denied

This does not reflect my own lived experience.

But if true, that means that Google can choose to not provide you a recovery service, which is functionally the same as them not having it.
