Right. This is, by the way, the sole innovation of Bitcoin. Describing a mechanism to establish a sequential order of transactions with finality.
Timestamping servers. Something like RFC 3161 or WebPKI's Certificate Trust logs.
That doesn't help you know the transfer is final, it just gives you a timestamp that the transfer occurred at which somebody reputable has attested to. You can't know that the owner didn't sign a transfer to some other buyer with an earlier timestamp.
How does the receiver of such a transfer know that the transfer is final? There's no way for them to know that an "earlier" transfer of same item won't show up days later.
