Then what you're saying is these rights don't help me at all (anyone can violate them at their own will), so what is the point of them? Announcing these rights to a dictator that wants to kill you won't save your life. It just seems silly to me, plus you hand authoritarians the language that helps them. They now say you have a right to healthcare, a job, a house, and on and on. And the government will provide it to you.
Freedom is a basic idea. There is no "right" to it, it is just the principle we want to base society on. I'd say it is described pretty well by the 10 commandments. Those come pretty close to describing the ways in which the principle of freedom regulates your unlimited freedom to do whatever you want.
There is a difference between "negative rights", which state that others cannot do certain things to you, and "positive rights", which pledge to give you things.
Negative rights are natural rights endowed by God.
Positive rights are contrivances of governments, and are not on the same level as negative rights because they can be taken away with the same pen that granted them.
You cannot write a law to take away your natural, negative rights. Even if you did write such a law, those rights would still exist but they might be violated.
Yes, people or groups of people (including governments) can violate the rights of individuals. Rights exist, they were granted by God, and they can be violated, but they exist as a framework for rational interaction with other people. It is not as if rights merely exist without purpose.
Rights will only be honored by people or groups of people that have enough respect for people to honor their natural rights. Part of the purpose of rights is that it a way for God to inform humans of how to interact with each other that they may get along and progress spiritually rather than be in conflict.
