I would gladly not vote if I didn't have to pay taxes. But if they forced me to pay taxes, I would vote, and vote them out of office. Then, without having to pay taxes any longer, I wouldn't vote any more... at least until the cycle started again.
So, you always vote to try to get people out of office, so they will stop forcing you to pay taxes? Have you had an success with this yet? You must do a lot of voting, since I'm pretty sure there is not one country with absolutely zero taxes. How do you imagine this society with no taxes? Do you have some economy and political system in mind?
Well, to answer your first and second questions, I essentially don't vote, because nobody is forcing me to pay taxes.
A country without taxes? All people are taxed, some of them just by getting out of bed in the morning. But not all people are taxed monetarily.
Monetary taxation does one major thing. It enriches those who receive the tax money, in an unfair and unrighteous way. Rather than paying taxes, buy what you want. If you want to use the roads, buy the rights to use them. If you want military protection, buy the military protection. If you want a Mars program, donate to it. Do you want schooling for your kids?, pay for it; why should anybody be forced to pay for schooling for the children of somebody else? There is no reason to be forced to pay something you don't want or don't get. Taxation is theft.
Further, in America, if the IRS attacks you for not paying taxes, it doesn't, really. Rather, it is some IRS agent doing some paperwork. Ask the IRS agent to show you the agreement you have with IRS laws. If you agreed to pay, then pay, as your agreement states. If he won't or can't show you the agreement, sue him for the injury of the hassle he is putting you through.
If the IRS takes you to court, they don't, really. The indictment always reads THE UNITED STATES OF AMERICA vs you. In the States, you have the right to face your accuser. Since THE UNITED STATES OF AMERICA is your accuser according to the indictment paperwork, require THE UNITED STATES OF AMERICA to take the oath, get on the stand, and testify to the harm or damage you have done to it, with evidence of the harm or damage, and proof that it was you that did the harm or damage. THE UNITED STATES OF AMERICA is paperwork. Paperwork can't get on the stand and testify to anything. Case dismissed for lack of your accuser testifying in court.
Suppose at the beginning of your trial the judge asks the prosecuting attorney what the trial is all about. The prosecuting attorney starts telling the judge what the accusations are. If you don't object to the prosecuting attorney testifying without having first-hand knowledge, and without being placed under oath and on the stand, and without clarifying if he is a witness or an attorney (he can't be both), and if he is a witness, why he wasn't called by the prosecutor on the indictment (THE UNITED STATES OF AMERICA), you just let "them" run all over you.
But you made your first mistake by hiring an attorney. An attorney is an officer of the court. When you hired him, you agreed to whatever the court wants to do with you. It looks like a case of conflict of interest, but it is not, because by voluntarily hiring the attorney, you voluntarily turned the matter over to the total discretion of the court system.
The point is, since none of us are required to pay taxes in America, but since most of us pay them voluntarily, voting or not voting is not a tax question.
