Remains to be seen what Libra actually would be. It is mostly at drawing board for now. I could use it if it had some compelling use cases. There isnt much privacy with financial transactions anyway.

Not especially simple to buy contraband using dollars electronically, over the internet. If we assume those contraints, there are existing solutions that actually work without as much immediate interference.

A dollar replacement with zero additional benefits (like those mentioned above) seems like the exact "solution without a problem" that existing "blockchain" tech was pretending to not be. TL;DR - this won't work!

I would also think so mainly on privacy ground and on the fact that Facebook is one of the companies that I trust the least. But I'm not keeping my hopes high when I see how people buy Facebook Portal for example (their tentative clone of Amazon Echo).

Has anyone bought a Facebook Portal? I've had the impression that it has all the market penetration of the Fire Phone.

I wouldn't use one if it was given to me for free.
