Let's play a game of predictions. Regardless of HN's opinion of Facebook (and regardless of my own for that matter) I predict that this thing will work. This is only one thing my crystal ball showed me. Facebook's presence in developing economies is massive. To the point of being synonymous with "The Internet" in a number of places. But they've had a nagging problem. People in these economies consume contents, but do…
IMHO, the Libra is at the same time too ambitious (in aiming for full capital convertibility across nations) and too timid (in entirely giving up monetary independence). A libra-usd, Libra-euro, libra-inr, etc. which allows countries to retain monetary sovereignty would have been easier for governments to accept. But then, Facebook can't say it's a new currency and circumvent KYC and other local regulations. But who knows? Stranger things have happened. The euro is a currency without a state. Maybe the time has come for denationalizing money.
