It is taught in almost all schools in all countries and we are usually ridiculed if we question it.

Without it we could have freedom.

Statism:

The brilliant idea that we give a small group of people the right to kidnap, imprison, harass, steal from and kill people so that we can be protected from people who kidnap, harass, steal and kill people.

Mahatma Mohandas K. Gandhi

The state represents violence in a concentrated and organized form. The individual has a soul, but as the state is a soulless machine, it can never be weaned from violence to which it owes its very existence.

John Adams

Fear is the foundation of most governments; but it is so sordid and brutal a passion, and renders men in whose breasts it predominates so stupid and miserable, that Americans will not be likely to approve of any political institution which is founded on it.

John Lennon
Our society is run by insane people for insane objectives. I think we're being run by maniacs for maniacal ends and I think I'm liable to be put away as insane for expressing that. That's what's insane about it.

Milton Friedman
Every friend of freedom must be as revolted as I am by the prospect of turning the United States into an armed camp, by the vision of jails filled with casual drug users and of an army of enforcers empowered to invade the liberty of citizens on slight evidence.

Adolf Hitler

How fortunate for governments that people do not think. There is no thinking except in giving and executing commands. If it were otherwise human society could not exist.

Quote from Lenin:
"While the State exists there can be no freedom;
when there is freedom there will be no State"

From Lysander Spooner:
It is true that the theory of our Constitution is, that all taxes are paid voluntarily; that our government is a mutual insurance company, voluntarily entered into by the people with each other; that each man makes a free and purely voluntary contract with all others who are parties to the Constitution, to pay so much money for so much protection, the same as he does with any other insurance company; and that he is just as free not to be protected, and not to pay any tax, as he is to pay a tax, and be protected.

But this theory of our government is wholly different from the practical fact.  The fact is that the government, like a highwayman, says to a man: Your money, or your life.  And many, if not most, taxes are paid under the compulsion of that threat.

The government does not, indeed, waylay a man in a lonely place, spring upon him from the road side, and, holding a pistol to his head, proceed to rifle his pockets.  But the robbery is none the less a robbery on that account; and it is far more dastardly and shameful.

The highwayman takes solely upon himself the responsibility, danger, and crime of his own act.  He does not pretend that he has any rightful claim to your money, or that he intends to use it for your own benefit.  He does not pretend to be anything but a robber.  He has not acquired impudence enough to profess to be merely a "protector," and that he takes men's money against their will, merely to enable him to "protect" those infatuated travellers, who feel perfectly able to protect themselves, or do not appreciate his peculiar system of protection.  He is too sensible a man to make such professions as these.  Furthermore, having taken your money, he leaves you, as you wish him to do.  He does not persist in following you on the road, against your will; assuming to be your rightful "sovereign," on account of the "protection" he affords you.  He does not keep "protecting" you, by commanding you to bow down and serve him; by requiring you to do this, and forbidding you to do that; by robbing you of more money as often as he finds it for his interest or pleasure to do so; and by branding you as a rebel, a traitor, and an enemy to your country, and shooting you down without mercy, if you dispute his authority, or resist his demands.  He is too much of a gentleman to be guilty of such impostures, and insults, and villainies as these.  In short, he does not, in addition to robbing you, attempt to make you either his dupe or his slave.

The proceedings of those robbers and murderers, who call themselves "the government," are directly the opposite of these of the single highwayman.

In the first place, they do not, like him, make themselves individually known; or, consequently, take upon themselves personally the responsibility of their acts.  On the contrary, they secretly (by secret ballot) designate some one of their number to commit the robbery in their behalf, while they keep themselves practically concealed.
