Exactly that is the reason we will never see blockchain in the governance. If everything within government become transparent, how the power mongers will function?? How the bureaucrats will make money? How the politicians will take the juice out of the economy?? How the police force will indulge in illegal practices?? Do you understand the gravity of this issue??
Maybe not everything has to be decentralized. Transformation must be slow but strong. Some adjustments can be made by the central authority. / Thank you for your comment.
You will never see a complete decentralized governance ever in your life. Because there are so many things in an efficient governance that needs to remain as classified. Some progressive governments like Japan or Germany probably will adopt the blockchain for better and transparent governance in some areas but largely you won't see much changes from majority of the other governments.
I have worked with government and beaurocrats earlier in my life. I have a macro level idea on how the system works in third world countries. Transparency is a big no-no in government offices!
