The Declaration of Independence states we are all entitled to "life, liberty and the pursuit of happiness."
Since you need food to survive and you will DIE without food, you are entitled to food.
Quoting from the John Cochrane article I posted:
Notice the progressive-passive voice. "Is every American entitled to eat?" Just who does what to whom?
The direct answer to the question, as posed, is, "Yes. Every American is entitled to eat. And on just what planet do you live that you think there are laws prohibiting Americans from eating?"
Since the question as posed is nonsense, we know it must have a hidden meaning. The hidden subject of the sentence, is given the food-stamp context, the federal government. What Scott means is, "Is every American entitled to have the Federal government tax other citizens to pay for his or her food?"
Stop and savor the power of the subject-free sentence, the difference between the stated question and its real meaning.
Even to that one the answer has to be no. There is no such law, right, or entitlement. That is a simple matter of fact. Scott knows that too. So, what Scott really means is, "Don't you think the Federal government should establish an entitlement that every American can have the Federal government pay for his or her food, from funds raised by taxation?"
On the third time, he almost actually said what he meant, with "is food stamps something that ought to be that ultimate guarantor?" Though "food stamps" is a pretty wimpy subject of a sentence. "Should the federal taxpayer be the ultimate guarantor through the food stamp program" is more accurate.
