If you earn a dollar, you get to keep about 50 cents. At some point, working more doesn't making sense. Some enjoy more leisure. Others work in the underground economy, thus creating a bifurcated society. To experience independence, one must be able to choose how to spend the fruits of one's labor.
Taxes take choice away from individuals and give it to politicians and bureaucrats.
We become as children, incapable of living our own lives, able only to follow orders. Actually that analogy gives too much credit to taxation, for children grow into responsible adults, whereas taxation reduces adults to dependency. Taxpayers are obedient or beaten, always begging for another scrap. Only taxpayers create the wealth that the government confiscates and then doles back out. If being human means anything, it means using one's mind to make decisions.
