A.) If you are born in this country, you are a citizen. Therefore you are a member. But you can leave when you are 18 if you feel the tax system is unfair.
B.) The government of the USA has control over the lands of the USA. If you live within those lands the government has control over then you are subjected to pay taxes. Just like if you live in a specific state you have to pay the state's taxes. People from Georgia don't pay Texas taxes, but they are obligated to pay Georgian taxes.
C.) This is a flawed argument, because it assumes that the state has control over the people. It doesn't, the state can't tell me what job to do, when I can go to bed, when I have to work, if I have to work, how long I have to stay here, stop me from leaving. The state can't do any of that, well unless I broke a law, and I wouldn't think you are advocating the abolishment of laws now are you? So what if I went driving drunk, what makes the government think it has the right to take away my freedom by putting me in jail!!! :roll:
Taxes are a necessity of life, you need to deal with that. Or you could boycott taxes, and everything the government does with them. Just remember to not use any road, unless you make it yourself. Oh and just turn in that drivers license you have, because it's was made using tax dollars. Oh, and quite your job, because your being "forced" to give up some of your paycheck to the government, and there's no way to get around that besides quitting your job. And just take your kids out of public school, no need for them to benefit because of evil taxes. I could go on, but I think you get my point.
