Does the Government Own Me?
No. Although the United States government and the states within it impose restrictions on what you can do, including things they do themselves, the state does not have any proprietary right over you or your body. Generally, you are not allowed to hurt yourself, i.e., you cannot commit suicide or abort your baby without first checking if the state and federal laws allow it and under what circumstances.
In cases of people who want to cut or dismember themselves or those with cannibalism fetish, they are forbidden from engaging in this behavior. The logic behind this is that governments can interfere when they believe what you are doing to your body is not in the best interests of the society. Generally, you are left alone to do what you like to do with your body. However, if the harm to your body outweighs the benefit to the society, the government can step in and stop you.
Nonetheless, the laws cannot stop you from abusing your body, i.e., smoking cigarettes, drinking alcohol, or even doing drugs. These are your "rights" which so far the government has not been able to interfere with or take away from you.
