I don't think any of these reasons would be true in a government that is neither corrupt, nor a puppet of its bank. The bad news, is that I don't know of any such country.
You can measure the corruption of a government by its restrictions on Bitcoin and Bitcoin businesses. The more regulations and bans there are, the more corrupt the government.
Without corruption, Bitcoin PROVIDES government with better governance. If every government transaction used bitcoin and each wallet were labeled by a message in the chain, and no stealth addresses, it would provide complete transparency for government activities, and creates a provably honest system of governance.
Higher corruption causes higher public investment, lower government revenues, lower expenditures on operations and maintenance, and lower quality of public infrastructure. The evidence also revealed that corruption increases public investment but reduces its productivity.
