lol, It is ignorance to blame all problems blindly on authority. Many people around me are complaining that some businesses only support electronic payment, which is a kind of market discrimination for those who have not received the education. And in China, e-payment has nothing to do with privacy or freedom. All payment tools can only be opened with ID cards, and some even need to upload recent photos of real people holding ID cards.

yes, and no, if private entities (non banks) are allowed to hold accounts for customers - than yes. As governments will have no real handle on how actually liquid those businesses are. What promises are their on your deposits? That could get out of hand very quickly. However, if only registered entities can hold accounts, than the opposite is true. Cashless society gives huge control to the government.
