I think that it can't be that some technology suddenly quickly replaced all the old systems in the economy, management, etc. This is a very long process. Everything is complicated. In addition, the new is not always better than the old. Modernizing the state infrastructure is a very serious process. It's not as simple as releasing the next model of iPhone.
We should not be talking here of replacing the system because eventually the government will approve blockchain and though blockchain will be widely used, the current centralized system will still be dominant as its controlled by the government, worse possible scenario is that the decentralized market will slowly transform into a centralized one since it's regulated by the government where they can monitor and control the law.
