That is more or less how title insurance started back in the day.

In 1800 land was sold in person only by people who knew each other, in front of other witnesses who knew everybody in town. It worked great, which is why some states (I assume like CT) never bothered with a registry. In the mid 1800s as land out west started opening up for settlement (skip the whole bad treatment of the natives) investors "out east" wanted to invest in land and ran into a problem: they didn't want to go out to the land, but they knew scams existed so they started hiring trusted people to travel instead and verify they property owner was really the person they were buying from. Some states have a registry and so you don't need that, the state tracks owners and verifies the people buying/selling really are who they say they are.
