They've already shifted their plan by a huge amount from decentralization to centralization and succumbed to the power of governments. No reason to believe it will not continue to happen in the future.
Party's over, goodnight, go home. Maybe Western Union will lose some profits though.
Though I do wonder how rules for international (country A => country B, or country C => country C, where C != the US) transactions will be applied. Since FB is a US company does that mean every single Libra user will be subject to US restrictions - even those which are legal in their country? Will Iranians be able to use Libra? What about Canadians using it to buy marijuana?
They said they will vet the people allowed to mine / process transactions on the network, so it seems like FB could easily be required to shut down a miner if the US government says they're doing money laundering or allowing people in Iran to buy medical supplies or allowing Canadians to buy weed or assisting with other illegal activities.
I'm sure banks have already dealt with this problem extensively. Libra seems like a very non-innovative solution - just another bank, by Facebook this time.
