After reviewing the Facebook hearing with the US Senate, it seems that the US government still holds a very strict opinion on Libra. With a huge user base of 2 billion people, if Libra works, Facebook will operate a very large monetary system compared to the US government's monetary system. That why US government will not let this happen. Now we can only wait to see what Facebook will do to be passed.
Facebook would have no choice rather than to comply with the US laws. Even though they get shifted to Europe or somewhere, US would do whatever necessary to make sure they won't exist very long. Decentralization and Privacy is hated by every oppressive governments equally around the world.
Yes, that's why David Marcus is still trying to convince the US government to believe in Libra, even if it is registered in Switzerland. The most compelling reason he gave is that if the US does not participate in this field, other countries like Russia or China will be willing to do and take the opportunity of the US. And US will never go slower.
