Well one of the features of decentralized cryptocurrency is that governments will not have the same power to implement “monetary and fiscal policy”. We do not want more government fiscal policy. The intent of these policies is usually to mitigate the effect of market discipline....let them be subjected to it as you and I are.
The Euro caused the Greek problem by allowing the Greek government to spend and borrow wildly without the market discipline that would have been applied to them if their currency had been Drachmata or for that matter Bitcoin.
