What an excellent ,detailed and well thought out post; you have outlined really well the advantages of a blockchain government. That's exactly what all countries on earth should aspire to. However, am sure most politicians would want to maintain the status quo, so they keep lying to us, not being accountable and directly benefiting themselves at the expense of the populace.
It would be wonderful to see a decentralized blockchain government in action, it will take time but eventually we may see it. In Kenya for example they are already incorporating blockchain technology in the lands registry for transparency and accuracy of all land transactions. The judiciary are trying to implement a blockchain too where they want to put all ongoing, ruled and settled cases. So that the information can be accessed at different tiers maybe protected with passwords.
We are taking baby steps but blockchain government is going to eventually come true in some shape or form. Thank you for sharing and I wish you a productive new week ahead :}
