Nope. You can't just issue money, and you have to accept the state currency in most places on Earth. Paying taxes using Bitcoin is mostly easier than using cash thanks to services that will do a bankwire for you, so what.
Look up "contra entry". http://desktophelp.sage.co.uk/sage200/sage200standard/Conten...
All business credit is issuing money, and as the contra shows you can easily settle debts with it.
"Paying taxes using Bitcoin is mostly easier than using cash"
Where do those services get the state money from? The service are providing the exchange for you. That's not paying taxes in Bitcoin. That is paying an exchange service to pay your liability in dollars for you. Exchanging a liability isn't extinguishing it.
The Treasury account at the Fed doesn't accept Bitcoin. At that's ultimately the bit you've missed. Follow the transactions through transitively and see if you can eliminate state money from the process completely. You won't be able to.
