Almost. Because Bitcoin is highly energetic compared to currency, it isn't all the way there. And novel attacks exist for digital currency that are not present in physical currency. Currency has to be tradeable with marginal cost nearly zero (will never be exactly zero), and in my view digital currency has this as an issue. The analogue for digital currency, when appropriately crafted and not a sh*tcoin, is gold. Hard to get, limited in volume, costly to secure and appropriately manage. Gold can be used for currency, but it is awfully insecure to hoarding and banditry.

Fiat currency solves a _lot_ of problems while also having limitations broadly railed against by digital currency advocates.
