They have to develop a "Private" Blockchain where they can change the Coin Cap at will to feed the constant debt demand and to artificially stimulate their economy with that debt.
Bitcoin should steer clear from any debt based economy and focus specifically on being a alternative Cash payment solution or a commodity to trade with. These "Private" Blockchains will only be a copy of their Fiat currencies, with the only difference being that the Coin supply can be changed with the change of a few parameters in the protocol/code.
This will be no different than the system they have in place now and the debt will just increase even further. Bitcoin or "Public" Blockchains are based on a open consensus and people will not increase the supply, because it will decrease the value of their current coins. < The people decide, not some government >
"Private" Blockchain currencies will destroy themselves, because it is based on the failures of the current monetary systems of infinite money supply.
That is why Bitcoin is the solution for the continuously increasing rate of inflation. Because Bitcoin's cap is immutable. So there is a limit. Unlike our fiat today wherein government prints and prints money that causes hyperinflation. And that is the reason why Government is having a hard time adopting Bitcoin because they can never change the Bitcoin's supply. They can never control Bitcoin.
