It is no crime to be ignorant of economics, which is, after all, a specialized discipline and one that most people consider to be a ‘dismal science.’… - Murray N. Rothbard

The State obtains its revenue by coercion, by threatening dire penalties should the income not be forthcoming. That coercion is known as “taxation,” although in less regularized epochs it was often known as “tribute.”
Taxation is theft, purely and simply even though it is theft on a grand and colossal scale which no acknowledged criminals could hope to match. It is a compulsory seizure of the property of the State’s inhabitants, or subjects.

Exchange is the lifeblood, not only of our economy, but of civilization itself.

"The most sanctified figure in American historiography is, by no accident, the Great Saint of centralizing "democracy" and the strong unitary nation-state: Abraham Lincoln. And so didn't Lincoln use force and violence, and on a massive scale, on behalf of the mystique of the sacred "Union," to prevent the South from seceding? Indeed he did, and on the foundation of mass murder and oppression, Lincoln crushed the South and outlawed the very notion of secession (based on the highly plausible ground that since the separate states voluntarily entered the Union they should be allowed to leave). But not only that: for Lincoln created the monstrous unitary nation-state from which individual and local liberties have never recovered."
