For some of the conquered people living under heel of the Roman Empire, this was virtually the case. Their economies had to go entirely underground. When caught, they were punished, tortured, and even executed.
So, the answer is, “Yes”.
The alternative is spelled out in the Declaration of Independence.
That makes no sense; you said Christians are obligated, legally and morally I presume, to pay whatever tax “Caesar” claims is due him.
Then, you bring up the concept of overthrowing the government.
Which is it?
It can’t be both.
Or are you claiming that you have to pay Caesar until you kill him?
