Aren't the so called big boys in the cryptocurrency space already an exact of what you just described? Ripple (XRP) and EOS are an example of a centralized cryptocurrency yet the community is patronizing them. If this is what we have to sacrifice for the adoption of cryptocurrency globally then I'm ok with government owned cryptocurrency although that doesn't mean I would be patronizing them. The development of this national cryptocurrency will skyrocket the awareness on cryptocurrency and probably enlightening more individual on digital currency.
We needs this government centralized coins so more individual can realize how important bitcoin is since it isn't operated in the manner those centralized coins would be. While bitcoin provides freedom, the government issued coin would just be a replica of fiat (mode of operation) on blockchain probably stablecoins.
