Long term, we need private money or it just gets traced / taxed / seized by the state anyway.

But truly private money makes for a bad store of value. You can’t audit the ledger, so a bug could create unlimited inflation that would be hard to detect.

So privacy is how you move money, not necessarily store it.

I tried to register on a website with an email @fiatjaf.com and the website had the spite to tell me they didn't accept "temporary email addresses".
