This is not surprising. The minute Libra starts operating it becomes the main money laundering tool in the world. Depending on how it's implemented it could easily topple the economies of smaller countries, and significantly increase funding for terrorist organizations and garden variety criminals. I don't see how any government, and especially the US government, agrees to any of that anytime soon.
A launderer or terrorist (actually ANYBODY - good or bad) would have to be the biggest fucking idiot to use Libra and expect the transaction to be anonymous or private.
I sincerely hope you were just whipping out the typical ML/T FUD and don't believe that yourself.
