What is the benefit of Libra exactly? Why not just set it up like WeChatPay or Paypal as a centralized database? I guess like gambling chips or video arcade tokens, the lack of belief that it's real money might confuse some people into spending it more freely. Another thing is is that they can take all the money that's paid into Libra and run a hedge fund with the reserves because they can write their terms and conditions so they can do whatever the heck they want with the "reserves" and not tell anyone what they're doing. Another benefit is that they can facilitate illegal commerce on facebook by letting people conduct cross border transactions outside of AML/KYC land that a PayPal like system would require. They can also tie identities to coin transactions to analyze transactions for further ad targeting. Did I miss anything?
