While I get where you are coming from, realistically speaking we do have to accept the "extortion" that comes with having a governing body. I am happy to hand over my tax Rands (Dollars), provided me and my fellow citizens can benefit from it.
The point here is that is in most cases a "de facto" contract between a citizen and his/her government. As this is a contract, the citizen has rights to oversight on how his/her money is being spent.
