Hacker with bullhorn: "Save your money! Accept one of our free tanks! It is invulnerable, and can drive across rocks and swamps at ninety miles an hour while getting a hundred miles to the gallon!" Prospective station wagon buyer: "I know what you say is true...but...er...I don’t know how to maintain a tank!" Bullhorn: "You don’t know how to maintain a station wagon either!" Buyer: "But this dealership has mechanics on staff. If something goes wrong with my station wagon, I can take a day off work, bring it here, and pay them to work on it while I sit in the waiting room for hours, listening to elevator music." Bullhorn: "But if you accept one of our free tanks we will send volunteers to your house to fix it for free while you sleep!" Buyer: "Stay away from my house, you freak!" Speculative economists take note: abundance is hard.
