No matter how hard you blockchain you're still under the law of the government. You still have to pay taxes in your country's currency. Your "decentralized" blockchain still relies on centralization. Your internet infrastructure is centralized and ran usually by the government. The power grid you depend on is centralized.
My point is your blockchain technology still relies on the government. China even outlawed Bitcoin mining. YOU ARE NOT GOING TO FIX POLITICAL PROBLEMS WITH BLOCKCHAIN.
