We should know very well that governments will continue to support centralization. It will not create a coin that supports anonymity or untraceable. This is against the government system.
I agree with you, the government will not make crypto coins. they would not want to support decentralization, because that would certainly hurt the country's economy. the government will definitely find it hard to collect tax. but there is still the possibility of the government using blockchain technology but not in the financial sector.
