Crypto seems like it's (at the moment) neither low cost nor low friction; did I misunderstand you?
Actually, it's obvious to me that this is the future - we want to share money in the same way and with the same ease we share thoughts and images ie inside chat systems and on social media. You don't need crypto to do this, but it's the best way of making a system anyone can join and trust.
Libra is going to be big unless it's artificially stopped, and that's my view, even as someone who would much rather see one of the current cryptocurrency systems win rather than a new Facebook invented thing.
If we hadn't ceded chat and social media to walled Gardens we would have solved this years ago.
