It is a mistake and perhaps Pollyanna-ish to believe a governmental entity has not and cannot exert control over a blockchain ledger system of any kind either by means of protocol or other methods. In any case, I find it highly unlikely blockchains will not be implemented by various governmental agencies. As a store of auditable data, they would certainly be more trustworthy than some papers filed away somewhere or in some given database.

Certainly a lot of banks seem to be interested, and if banks can find a use for them I can't see why not governments as well.
