In the end, if Bitcoin is the money everyone is using, the State will have to start accepting it for the payment of taxes.
This will have many advantages for the state, as they can "Micro Tax" activities; something that is beyond the ability of the Geriatrics to conceive.
There will be an interim stage however, where the State demands that you pay it in its money, meaning you have to convert Bitcoin to fraudulent fiat. They will see, as they need to change the exchange rate twice per day, that the situation is untenable, and this will spur them on to switching to Bitcoin.
Bear in mind that once they have collected their own money as taxes, no one in the real economy will accept their money for goods and services, requiring them to buy Bitcoin just to pay salaries and live.
There is another scenario however, that indicates that the life of coerced money forms can persist indefinetly if properly managed:
THE TALLY STICK.
The Tally Stick was literally a piece of wood sawed along its length with a random zig zag that the British Crown would accept as a payment method for settling tax bills.
The power to enforce payment methods backed by violence is how this worked so well:

It's hard to describe the great depth of genius behind the concept of the Tally Stick. By doing this, the crown managed to create money out of nothing, and build a sound economy on it, whilst remaining at its centre as the essential manager.
Bitcoin with its jagged edged keys made of text is very much like a Tally Stick, but without an issuer or the need for saws or supervision. All of this is missed by the vast majority of Bitcoiners because they're ignorant.
Nevertheless, it is possible to build different kinds of economies on Bitcoin, and if used by the replacement central banks, can be the fundamental base layer like the Tally Stick.
FASCINATING!
