I strongly disagree with that. Gold fails because you can't take immediate, frictionless, settlement across any border. It fails because it's extremely difficult to audit efficiently and remotely. It fails because it requires a trusted agent to manage the ledger between it and the paper that rides on top of it (the paper that makes the units divisible and transportable). You obviously know all of this. Why do you think it becomes centralized and controlled by central bankers because of coffee transactions (which I can conduct in a noncustodial way right now)? I'm confused.
