Smart contracts aren't something that can kick the governments out, nor can hold something so important and set it into stone. It takes a lot more than that in order to replace the government and have the people believe in what you are saying. While it's true that a lot of people are already fed up with the governments' control and lack of actual welfare to their citizens, but is our current society ready to make the leap away from what's already in place for a few millennia now?
Crypto can be, at most, a way to work around unjust restrictions imposed by the governments, but definitely not something that will overthrow or replace it.
Right, but I think some people are overthinking what Bitcoin is and was supposed to be and do. Bitcoin is changing lives but as far as replacing fiat as I have seen some people speak about and replacing Government is still a long way off for me. On a global scale, the adoption of Bitcoin is still very little and until we have that global adoption and acceptance as Fiat is, it will still save as a speculative and Investment option.
