As long as there is a means of conversion you can start with anything and end up being able to pay your taxes. You can’t directly pay taxes with your time and skills, but you can trade your time and skills for USD, and then pay your taxes. You can’t directly pay your US taxes with the AUS dollar, but there is a market where you can exchange that for USD, then pay your taxes. The logic is inclusive of BTC, which makes the ideology that BTC is bad because you can’t pay your taxes with it, at very least, murky.
