Argument: People are obligated to offer support to others when it is a matter of survival
"Libertarianism". Standford Encyclopedia of Philosophy - "A second objection to full self-ownership is that it denies that individuals have an obligation to perform actions that help others, except through voluntary commitment. Some authors who endorse a form of self-ownership—such as Locke (1690) and Grunebaum (1987)—hold that one's rights of self-control are limited by an obligation to provide aid to others when the aid is necessary for their basic survival. Such authors thus reject full self-ownership. Those who reject the obligation to help the needy typically do so on the ground that it induces a form of partial slavery."
