Bitcoin is facing many issues right now and it is hard to deal every one of them. That's why as a community we need to help and support this innovation. And currently, the main issue that people are throwing to bitcoin is its legality. I personally think that bitcoin should be legal and should be recognize as a legit currency. What do you think will happen when the government finally recognize bitcoin?
Governments have very different priorities, [depends on developement/political caracteristics of each country] and decentralization doesn't tend to be one of them. In fact, government digital currencies could herald a new era of centralization, posing serious questions about privacy and the viability of true cryptocurrencies like bitcoin. This is the main issue of Bitcoin with governments!!
There's also some larger conceptual issues at play here; Bitcoin has proven that it's possible to create money outside of government-based financial systems, which forcing governments and central banks to ask questions about their role in the economies of the future. In my opinion, a digital currency which is backed, issued, and tracked by a government or a central bank authority would not be a cryptocurrency. So, governments and central banks should not have any major role in the economy of the future.
