I think you’re right, Poly.
Metaphysically, they are different. But rather than metaphysics, I’m talking ethics. Libertarianism is an ethical philosophy derived from the Noncoercion Principle.
In libertarian philosophy, noncoercion and freedom are synonyms. In other words, freedom is the absence of coercion. A context of peace and honesty, when enforced, provides for every individual the maximum possible freedom without robbing freedom from some other individual.
The ethical concept of ownership follows logically from the Noncoercion Principle. Though metaphysically you might own your land in a different way than you own your self, ethically they are the same. It was your mind and your body that you traded for wages so that you could purchase your land and your trinkets. You used your mind and body as capital for economic transactions.
With respect to your three questions, you can sell or mortgage anything you like that belongs to you. It might or might not be morally sound. In any event, it is not the business of man to define morality for other men. But ethically, you are neither bound to nor prohibited from selling whatever belongs to you.
A man cannot force you to sell, and you can force no one to buy. But if you are dealing with another consenting adult, and you have decided that you prefer to be his indentured servant, and he has decided that you would be a good one, thus by the two of you freely and willfully consenting, what business is it of any other man?
With your third question, however, you ask for something that is not mine to give. While you could petition an employer for a redress of grievances, or protect yourself from self-incrimination with your wife, no one will put you on trial but a government. A “right” that is given by a government is no right at all, but merely a permission that we hold at its whim. I have no right to a speedy trial to sell you. If I am to go on trial, it will be when they say and not when I say.
And I will have just a spot of tea since you offered.
