It will never be used as a general currency by the man on the street.

For example in the UK we have Direct Debits which are backed by the DD Guarantee. If a DD is wrong or fraudulent the bank must refund you without question and they initiate a DDIC (indemnity claim) against the creditor bank. This could not happen with Bitcoin.

Same for problems such as push-payment fraud - they are rolling out confirmation of payee to try to tackle this. How could Bitcoin be a viable payment method in it's current form when addresses are anonymous (in the context of PPF)?

The only thing that happened in El Salvador was a public politician making a populist statement.

It would make sense to point to Venezuela or Iran, but those examples don't get much attention for some reason.
