...it's not stealing if you willingly give up something.
For the umpteenth time, I do not willingly pay tax. I pay tax because I don't want to:
a) Go to prison;
b) Leave my friends and family;
c) Live off the work of others.
You can call those 'choices' if you want - same way as if you were mugged at knifepoint in the street, you might 'choose' to give up your wallet to avoid being stabbed. Doesn't make it voluntary, does it?
For the umpteenth time: You choose to live your life this way, so that doesn't make it involuntary, does it? What does your friends or family have to do with this? You chose to stay with them. Choices you all made.
And d) Earn under the tax threshold, but you don't want to play the game this way, so you willingly choose to pay the taxes on the money that you owe. You can't get a free ride this way I'm afraid.
