True. Governments creating their own digital currencies is not a big threat but rather a good opportunity because this will lead into a faster and massive adoption for crypto. People will be now taught how to use digital currencies for them to create cashless transactions which is more convenient compared to fiat transactions. And when the time comes that bitcoin will be develop as a legal currency, hopefully they will start using it too even as an alternative one.
It seems you are not seeing the threat, until not long ago governments were looking for ways to shut down cryptocurrencies but after they realized they cannot do that despite their incredible power they are moving to the next phase which is to create competition against cryptocurrencies, most people that are unaware of the real reasons for the existence of cryptocurrencies are not going to be able to tell the difference between bitcoin and those centralized cryptocurrencies and since those coins will be backed by the government and they are accustomed to use their fiat they will have no problem adopting those coins.
Yes, Governments first said that it is a threat and now after they realized that it is not that easy to shutdown cryptos, they try to go an other path. We could compare it with the cold war but of course without bombs but with competitive products.
