I think it's important to point out that libertarians like the OP are complete and utter charlatans. Everywhere their ideology has been implemented has been a catastrophic failure just like Chile under Pinochet or Bolivia only a few years ago. They want a world where everything is privatised whether it be schools, prisons or the police force. This is so they can create new business opportunities for their pals in big business and ensure zero taxes on themselves. They want to abolish all welfare payments and force the poor, needy and unemployed to beg for everything. Their ideology is always accompanied by huge unemployment and poverty wages for the working class while industrialists, landlords and speculators become millionaires. Libertarians are the real parasites. They want to create a society where the working class is impoverished while all the wealth they create goes to line the pockets of of capitalists, investors and speculators who never work nor pay any tax.
