You are NOT property, You do NOT own yourself, and you may NOT do whatever you wish with yourself. You are a human being, not chattel. You won't find anything about "self-ownership" in the Constitution.
John Locke disagreed with you. He said:
"Every man has a property in his own person; nobody has any right but to himself….” Two Treatises on Government
As did Jefferson:
* Under the law of nature, all men are born free, every one comes into the world with a right to his own person, which includes the liberty of moving and using it at his own will. This is what is called personal liberty, and is given him by the Author of nature, because necessary for his own sustenance.
o Legal Argument (1770)
or
"We hold these truths to be self-evident, that all men are created equal; that they are endowed by their Creator with inherent and inalienable rights; that among these, are life, liberty, and the pursuit of happiness;"
What do you think the right to life means? It means the right to OWN your life. It is the first property right. The right to life is more than just the right not to be killed. It is the right to live your life as you want as long as it doesn't infringe other's rights.
If you believe we don't own ourselves, you have necessarily placed that ownership in *society*, to be used for whatever purpose the Mob wishes.
"You won't find anything about "self-ownership" in the Constitution."
Because it was already a cornerstone of their ideas about property. There is no property rights without self-ownership.
"nor shall any state deprive any person of life, liberty, or property, without due process of law;"
My life is MY property, to be used as I wish as long as I do not deprive anybody else of their life, liberty, or property. And I will defend that property with the life of anybody who tries to use me as a means to their ends if it came to it.
