Can’t that be done through easily through Paypal ? (or Western Union, I just never tried)
And while Libra definitely isn't perfect I think the set of trade-offs they chose are pretty reasonable. Another advantage over Venmo, Western Union, etc. is that the Libra will be run by a multiple independent companies, instead of locking you into a single company which is the case with the currently existing solutions (with the exception of SEPA).
At least in France, people actually use apps like Venmo for person to person transfers (or cash, or cheques, but they're on their way out).
We mostly use SEPA for either automatic bill payment authorization, or big transfers. No one will start a bank transfer and ask for their friends IBAN to pay back two beers.
All of that will be tied to a real identity, but I am not sure Libra will also be completely free of these ties. There must be a point where to use your wallet you’ll have to justify your identity (i.e. above some amount or some kind of purchases you hit KYC requirements)
