Would you allow other companies to deliver letters and to deliver stuff inside mailboxes? I find it disgusting that a company with a monopoly on those two services still can't make a profit.
Someone just bringing whatever shit they want to my house? Junkmail needs to be deregulated? Everytime I hear the "notions" of the libertarian/hypercapitalist ilk it just sounds like "What if your life could be even shittier than it is now?!?"
