But either the government blockchain can get forked/modified by people with enough resources, in which case it’s not reliable, or it is certifiably controlled by the government in which case there’s no point to it being blockchain.
Only if you make a system with POW and miners. With a DAG it should be possible to create a network where for example every person that issues a transaction (saving stuff into chain) validates two or more previous transactions on their device (or node if you run your own) using either PoW or PoS depending on what you want to achieve.
