They simply need to record the location of the property markers. They could even use paper. The problem is that they don't have surveying equipment and the training to use it so all they have is the sticks. As others have said, you can't (usefully) represent ownership in the blockchain because ownership can change or be made irrelevant outside of the blockchain. While blockchain wouldn't be useful for this, a host of cryptographic tools would be. If a country used signed survey data they could prevent a host of crimes and bugs changing boundaries, and if they issued signed land titled you could check their validity offline - helpful for remote areas. They could be tied together entry to entry, like a blockchain, to assure that no records "go missing". There could be a single-core proof of work stored regularly, checkpointing the data, to prevent the country's IT team from rewriting the whole database. It just doesn't need to be "a blockchain" because there is a centralized authority who we all follow, if not trust, so the decentralized thing isn't that important. And we don't need to limit publishing so we don't need a currency.
