This makes the phone the point of weakness, as there's no access when the phone is missing
I suppose that depends on how or where you store your passkeys. I use Bitwarden (technically Vaultwarden, but functionally the same for this purpose), and mine are stored as part of my Bitwarden data. That means I can use them in my desktop web browser, my phone, etc.
Your other points are definitely valid, but making the phone the "sole point of authentication" isn't an explicit weakness of Passkeys as a technology, only the terrible implementation by major tech providers (and lets be honest, device/vendor lock-in is certainly not an improbable explanation for this).
