Not a good news at all! Corporate buying into bitcoin market is still somewhat good news but it's not same when government bodies buy into it. It will further centralize the network and government will have the power to manipulate the market to satisfy the banking lobby. That's not good at all!
We will see temporary liquidity flow into the market for sure but seriously need to think - at what cost that might come to us in future.
It still takes time before the governments plan on centralizing Bitcoin takes place. They still need to have control over the international Bitcoin market and that means they need to have at least half of Bitcoin in circulation. Centralizing Bitcoin won't be easy especially that we have a decentralised ledger.
As for now, governments engaging into Bitcoin is considered as a good news as it will push the Btc price and adoption higher. So, yeah one thing I have to agree with is your last statement.
