Reducing your attack surface to the people who can/are willing to gain physical access to your device to use a passkey is orders of magnitude smaller than a password that can be taken and used from anywhere in the world, without having to get up from their computer.
If someone really wanted to gain access to something of yours, they could take you and your family hostage and force you, but that is an incredibly small attack surface. "What we have accomplished" is shrinking the attack surface, not perfect security.
