Critics of the libertarian philosophy often complain that libertarians see rights violations all around while denying the existence of things like welfare rights. So, libertarians, how many rights do people have? One (say, the right to life)? Three (life, liberty, and property)? Or an unlimited number (the right to do this, that, and the other, ad infinitum)?
Sheldon Richman argues that people have only one right: the right not to be aggressed against. All further rights are simply applications of this fundamental right.
