It depends on which government issued it and its motive on issuing it in the first place.
That could be something - however, it's safe to assume that all government issued crypto is going to be centralized, and the controls are essentially still handed to them. There is absolutely no change. If they want to actually let their citizens use a decentralized crypto, they would have done so with existing cryptos like Bitcoin.
For me, as I said, I would avoid centralized cryptocurrencies entirely, regardless of which country issues them. They simply aren't backed by anything, even if they claim to (cough cough *Petro*), since there is absolutely no guarantee they are going to redeem their promises.
One drawback i could think of is that coins issued by the government is most likely politically driven. Meaning, its aim isnt to offer a decentralized solution, but maybe it's just more ways getting away with corruption.
Anything relating to issuing one's own currency, on any platform, is politically driven. Just like Venezuela's crypto-fiat. Not sure how it could help corruption, though.
