Though, it's very difficult to see governments being positive on bitcoin on a worldwide scale any time soon.
Governments not being in consensus is a great thing. I don't mind the mixture of governments being 'for' and against Bitcoin. It keeps things in balance, because if governments globally would agree that Bitcoin is a great invention that should be adopted, they just as easily could pool their efforts and ban the crap out of it.
Bitcoin so far has gotten an easy ride through its existence. I really believed that we would face more resistance from governments, but they have been pretty mild overall.
I think that it would be beneficial if the government would support bitcoin as an alternative payment platform. Assuming that they support it, an imposition of tax on every transaction may happen but it would provide benefits to the public through healthcare systems, etc.
The downside is, it defeats the purpose of having a decentralized form of payment which is free from any third-party regulation. In addition, bitcoin's volatility is what makes it attractive for investors as one can yield large amounts of profit in a short amount of time.
It feels like fiat was made by the government without them knowing the risk as to what it would potentially lead to in the central banks artificially inflating it so much.
Inflation is in fact, a great thing but what makes it harmful is hyperinflation or deflation. Inflation is a tool to control the value of money. Some countries specifically target a percentage of inflation quarterly (i.e. 2-4% of inflation).
