governments fear everything they cannot manipulate or control. even the banks fear Libra and cryptocurrencies. the banks have probably pressured governments to intervene. let us remember, however, that Libra is not truly decentralized.
When it comes to LIBRA, it is not the decentralisation that the governments are afraid of. They are afraid that the centralisation of money is moving out of their control.
I predict that LIBRA will take over monetary supply in the whole world within 50 years.
If you think about it, it is both good and bad in many ways.
