Perhaps we just need to wait for further developments. Especially because before the release of the coin Libra is still long. Of course, having access to the data of its users, and this is almost a third of the population of the Earth, if Facebook still controls their financial flows, it will turn into a big monster, where much of the information about the population of the Earth will be concentrated. In my opinion, it is very dangerous.
Whether we wait or not, Libra is coming,,, and this is exactly what all the regulators are concerned about, that Libra is coming and it will arrive before the laws have time to adjust to it. And if you know Facebook it has enough money to develop and push this out asap, it will be here when we least expect it, earlier than scheduled.
What you said about their data is exactly also the main concern since they have already used it maliciously in the past.
