Libertarianism is rooted in the concept that every person owns his/her own body and has the right to life based on that principle. God gave me to me. He didn’t give me to the State. As the owner of myself, I am also the owner of the fruit of my labor, because if someone else owns the fruit of my labor, then they also be default, own a part of me as well, since they can compel me to produce. The only one instance that we voluntarily give up ownership of part of ourselves is in Holy Matrimony, in which “two become one flesh”, and a spouse’s rights include the right to demand the marital debt, i.e., sex.
So, if I don’t have a right to my own body, who does? If God didn’t give me myself, who or what did He give it too? And what part of this concept is “evil”? Is it evil because you don’t like it, because you cannot control it? By claiming that you have the right, through the mechanism of government, to tell me what to do with myself, then you are claiming partial ownership of me. THAT, my friend, is evil. Jesus Christ demonstrated this principle of self-ownership when he told the Apostles “they do not take my life, I give it up willingly”. You don’t have the right to claim ownership over anyone but yourself and your spouse. In fact, you cannot even claim ownership of your children. You are given stewardship over their lives temporarily, for if you claim “ownership” of your children, then you fall into the same trap that pro-abortion people do, because if you own your children, even in utero, then you can do with them whatever you want. However, if a person owns him/her self from the moment of conception, then noone has the right to commit violence to him or her, and the one who commits violence against another is a murderer, or a thief, whathaveyou.
