Minors - taxation without representation?

Ok than, taxes are absolutely necessary for minors and for people 18+. If you are a minor, you can drive a car. (16, learners permit, or something like that) Well your on the road. The government would be nothing without the taxes you give them. What the government SHOULD be is more like a passage through which money is collected and spent back into out county for our needs, not on some "weapons of mass destruction" brigade.

Would we really be better without a government, without any kind of defense from foreign countries. Without taxes, government is not helping us there.
