That’s not what’s being discussed. In other countries that operate under what’s called the Torrens title system, the government maintains an
authoritative central land registry. If you wind up in a legal dispute about ownership of a piece of land, the judge looks at the government books and is bound by what they say (with minimal exceptions).
We cannot have such a national registry in the United States. We could have 50 independent ones, but the few states that tried it have given up and reverted.
