None of your examples are all, at the same time, immutable, public, or ledgers. The Georgian land thingie is the most interesting, but a Georgian judge could definitely order a change in ownership due to incorrect data entered into the ledger, so it's not immutable.

There seems to be a misunderstanding. The ledger is immutable. That doesn't mean the state is immutable! Immutable state is not very useful. A judge could absolutely order that the ownership of some parcel is changed, but the change will appear as a separate record and everybody will be able to see the change and nobody can credibly deny that the change happened, not even the judge.
