Blockchain is unnecessary complicated, for example, it has mining, rewards for those who add new records, even VM and scripts and all of these are not needed for a government registry. I do not need scripts within a land registry.

replydepends on configuration, you can make any traditional web service replicated (replication is one and only thing that protects data in decentralized ledger, same as DNA is stored in every cell) using something like CometBFT on top. Mining/PoS or VM - all optional.
Clearly, you would scope the features and choose implementation options so that it makes sense for the use case. Mining (ie PoW and/or Nakamoto consensus) is clearly inferior to any deterministic consensus here. A cryptocurrency isn't necessary and would be a distraction. But at least some limited programmability could make sense (eg for escrow).
