Monday the SCOTUS confirmed our natural right to self defense, including the right to use a hand gun for that self defense. The court did not grant us a right, it merely recognized the natural right and that the government is prohibited from usurping that right.
Libertarian ideology is based on natural law or unalienable rights. The two basic principles to libertarian thought are property rights and non-aggression; Property rights being based on the foundation principles of life, liberty and the pursuit of happiness. This means that you own yourself, and the product of your activities, and as such can use yourself and your property as you see fit, providing that use does not infringe upon the rights of another. Non-aggression ideology meaning nobody should be permitted to use force against another except to protect their rights.
The key point is no right ever confers an obligation on another. You have a right to freedom of religion; this does not obligate someone else to build you a church. You have a right to freedom of speech and freedom of the press, this does not obligate another to broadcast, print, read or listen to your speech. You have an individual right to keep and bear arms, this does not obligate another to provide you with a gun.
Everyone needs food; this need does not give you the right to take food from another nor to require another to provide you with food. Everyone needs shelter and clothing, this need does not give you the right to take those from another, nor to require another to provide you with shelter and clothing. Without a doubt the single most life prolonging and health benefitting technology is modern plumbing. The clean safe delivery of water and fast efficient removal and disposal of human waste that modern plumbing has provided has done more to prolong and benefit everybody’s lives than anything in history. Everyone needs water and sewage services, you do not have a right to water provided by others. If you don’t pay your water bill and it can and will be turned off regardless of your individual need. Your need for water does not obligate another individual or the government to provide it to you.
Many totalitarian governments (and the UN) confuse needs and rights. Totalitarians want to classify individual needs as rights. They do this because in a society it is the government’s job to protect the rights of its citizens. If everybody has a right to something, the government tries to insure that the right is administered justly. So if you have a right to food, it is the governments job to ensure that everybody gets and equal share of all the food and no one person receives more or less than another. This gives the government control of all food its production and distribution. By making a need a right the government can justify taking liberty and giving more power to itself.
You have a right to your own property. Theft is the violation of that right. You therefore have the right to defend your property; this right does not obligate anybody else, or even the government, to protect your property. The SCOTUS as repeatedly ruled that the government is under no obligation nor responsible to protect any individual citizen or their property. You cannot sue the police for failing to protect you or your property.
Your right to life, does not and cannot obligate anybody else to provide for your life’s needs. The right to life means that your life is your own, and you are free to do with it as you see fit so long as you don’t infringe on another person’s rights. At times in your life you may need the services of a doctor, nurse, ambulance, etc. Your need for these services does not obligate somebody else to provide you with them. The only reason to change health care from a need to a right is to give the government control of 1/6th of the world’s most productive economy.
