Oh and please cite (philosophers, courts, stand up comedians) who say that is the purpose of civilization and how widely they are accepted?
Er... are you joking? Are you trying to tell me that one of the purposes of civilization is
not to protect its members? A society that doesn't protect its citizens is not a society; it's just a bunch of people living near each other. But here's one reference that you might find useful:
We the People of the United States, in Order to form a more perfect Union, establish Justice, ensure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
I'll try one better.
Thomas Hobbes famously called human life in its natural state as "solitary, poor, nasty, brutish, and short." Civilization's purpose is for man to rise above his "natural state." In other words, laws designed to limit our violent self-interest. John Locke clarified this purpose:
John Locke said:
[Civilization is imbued with] a right of making laws, with penalties of death, and consequently all less penalties for the regulating and preserving of property and of employing the force of the community in the execution of such laws, and in the defence of the commonwealth from foreign injury, and all this only for the public good.
With such a system in place, guns become irrelevant. They are a form of negative consequence for actions that are replaced upon the agreed upon-penalties enacted by the state. In fact, it is more effective then guns. You cannot enact a penalty on someone (i.e. shoot them) when you are dead. Civilization, however, can through its laws and enforcement mechanisms. Guns do not protect you in any meaningful way because you have a justice system in place. It is similar to the theory of Mutually Assured Destruction: civilization is our second-strike capability. Guns, much like nukes, have become a rather irrelevant weapon. Having a gun, therefore, is not only pointless, but goes against the purpose of civilization.
Even just having them to hunt goes against the grain of civilization.
Thomas Paine said:
It is always possible to go from the natural to the civilized state, but it is never possible to go from the civilized to the natural state. The reason is that man in a natural state, subsisting by hunting, requires ten times the quantity of land to range over to procure himself sustenance, than would support him in a civilized state, where the earth is cultivated
Unless you are a farmer (or living in wilderness), you have no reason to hunt. In a swift one-two punch, the top two reasons for gun ownership (protection and hunting) have been stripped away. Now it is time to talk about the third argument: The 2nd Amendment. First of all, to assume something is a right because it is written down is foolish. I am sure that if the Bill of Rights had something saying that Abortion is a Right, many people would disagree with that. Rights must be reasoned and justified. Since protection and hunting have been dismissed as reasons for gun ownership, we must talk about the real reason behind the 2nd Amendment, reproduced here:
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
This, in conjunction with other writings of the founders, has a clear meaning: when Civilization fails, it is up to trained citizens to maintain the order. It is the only piece of the Constitution maintaining the right of rebellion. The freedom of the State is not secure, the People are supposed to secure it themselves. It is a defense mechanism against the state turning into a tyranny. A state cannot credibly threaten a trained and armed citizenry.
Except they now can.
Nobody can effectively challenge the U.S. military. If the citizenry rises up against government injustice, it will quickly be put back down. The most famous example was the U.S. Civil War and that failed. Now there is a simple technology gap. The U.S. military has all the best toys. A .45 will not do much against an armed solider with a semi-automatic and that solider will not do much against a modern tank. Therefore, guns are still largely irrelevant because they cannot effectively perform their third function. In fact, the best way for the citizenry to now threaten the government is through peaceful organization and arming of the minds. An organized and thoughtful citizenry is a much more effective agent of revolution than a sidearm.
In modern Civilization, guns in the hand of the citizenry is an archaic throw-back to when we had no civilization. We are no longer a frontier nation. Education is now the greatest weaponry the citizenry can use. Being active and thoughtful is the only way to now currently fulfill the relevant third function of guns.
That or steal a tank.
