They have to do that, just like all corporations have to list the risk factors of owning their stock or various business ventures. Look in any annual or quarterly report and you'll see basically the same statements. They're covering their asses legally--and despite what was written about Libra, I'm certain Facebook plans to press ahead with it despite all the regulatory risks.
They will listen to what the government objects to the most and just release a version that's more reasonable even though it won't be decentralized.
Yeah. If Libra is meant to be a stablecoin, the government is going to have lots of problems with it. If Libra's price was determined based on market forces, that's another story--it would be like a security almost. I'm very curious to see how this all plays out. At worst, it'll get people's attention focused on cryptocurrency and might actually help bitcoin in the long-term. I have a feeling that Libra itself won't be too successful, but we'll see.
