If they deleted the blockchain db from the nodes, this is still lost.

Blockchain doesn't have anything esp. to do with data loss. It solves exactly one problem which is distributed double spending in accounting ledgers.

A blockchain solves the problem of consensus under Byzantine faults. Payments are an incidental use case, and not even a good one because managing payments including avoiding double spending can be achieved with a weaker primitive than consensus.

I suppose the idea could be that you have several different institutions holding the same data, which they know is valid because of the Blockchain.

No. Blockchain is made for managing transactions between untrusted parties. In case with a land, there is an authority managing the registry, so a standard relational DB (with optional digital signatures) is the bets option. Why someone wants to use a tool, not good for a specific purpose, for that exact purpose?

"X is made for Y" is inside-the-box thinking
