It sounds persuasively, I should say. Though I'm sure a lot of people won't agree with you. I have recently looked through cryptocurrency blogs (of course, all of them, have discussions about Libra) and noticed that many people are going to use this currency and don't see anything bad in it. But there are and always will be people who make money and those who lost it.Thing is, Libra is neither a cryptocurrency because it doesn't use a blockchain, nor is it decentralized.
Zuck is just jumping on the hype train.
In reality Libra is a security that is ruled and regulated by a consortium aka. the Valley FED, which works as unit of account.
The technology could be a big leap towards improvement of global payment, but I guess nobody wants Zuck to be the ruler of global payment, right?
