Enjoy this hamburger, which I have produced for you. I hired laborers, raised and slaughtered and processed the cows. I saw that the beef was transported from my butcheries to your house, and now some of the hamburgers are yours. Enjoy.
Your bill is in the mail, you will pay me $8 for each hamburger I have had produced for you, whether you choose to eat it is your own prerogative. You will pay me because I have had the hamburger made for you. It doesn’t matter that you may not want the hamburger now, nor may you have ever wanted it. It is of no consequence to our arrangement, if you happen to be a buddhist or a vegetarian, or if you have any other moral qualms against eating animals. If you decide to eat my hamburgers, and are not satisfied with them, you may not request a refund. If, after this incident, you decide you’d prefer to purchase your hamburgers elsewhere (until and unless I decide that nobody else can produce hamburgers), you must still continue to pay me for the hamburgers I will undoubtedly continue to produce for you.
I did not have the hamburgers produced because you wanted them, but you owe me for them because I had them produced.
Sound familiar? It should.
