Jesus said give to Caesar what belongs to Caesar. I take this to mean taxes are legitimate.
God repeatedly condemns unjustice weights and measures. That's what money printing is. Initially we trusted banks with so much gold, but the government kept changing the value of the money. We trust them with the value of our labor, but they trick us out of that value by counterfeiting it. This is not taxation, but theft.
I don't even agree with the common Reformed view that Romans 13’s description of governments bearing the sword is intended to be exhaustive. Governments may try to do other things, like build roads.
Without their counterfeiting machines, however, I think governments would be severely limited to only a few very important functions. #Bitcoinfixesthis
