Libra has been discussed a lot in the past but I don't expect it to launch anytime soon as there are a lot of legal hurdles to them right now.
Facebook is based in the US and the United States has only one central bank that can issue money. I think Facebook won't be able to do that without the amendment of the law.
yes I think it is like that too, that Facebook still has many obstacles in launching their own coins, in fact from 2019 - 2020 there have been no new developments from their project. because this is still against the law in that country, especially the US. crypto has not been well received by the AS country.
