Otherwise; his monetary musings are kind of mess up. From points in a computer game (Roblux), over proof of work distributed cryptocurrencies, to international interbank settlement using swift, to daily mobile payments replacing cash or card. It is not the same stuff. What China is doing foremostly prudent. It is about controlling credit creation. Not just limiting credit creation but also expanding it (or getting similar effects by using time limited money which obviously has faster velocity). If you give all your citizens an account at the central bank then your traditional bank disappears and with it the goes credit creation done by it. China and Western states for that matter can already do all the surveillance they want (using your credit card transactions or your mobile phone). As for payments between countries: This is not a technical problem but a problem of trust in currency and the credit extended.
