So that 50% attack results in someone taking all the land? No thanks.

It is a poor idea to use blockchain for government registries. If you want transparency, simply publish signed daily updates and that's enough. Just use simple DB with backups, and optionally, a printer printing changes on a paper.

Merkel tree audit log of the data, the poor man's Blockchain, works fine and good enough. Now you have a db and you can claim to use a blockchain for pr reasons.

Yeah, the overwhelming majority of the benefit of blockchain here is just gotten by making the data public and signed.

Now you may argue "that is a blockchain, not every blockchain is associated with a shitcoin" but to be frank that ship has sailed, if you wanted to defend that you'd have had to do a lot more work over the past decade.

A blockchain is essentially that, just with the daily update that's being signed also including the signature and hash of the previous day.

Blockchain as a technology is actually useful here. It does not mean automatically that blocks have to be mined by third parties, although pseudocurrencies have gone that route for decentralization reasons.
