VIRGINIA POSTREL: There’s No Free Locavore Lunch: “Patronizing local farmers who produce in small batches tends to cost more. You may find some peak-season bargains at the farmers’ market, but there’s no such thing as a free locavore lunch. Getting fruits and vegetables only from local farms necessarily limits variety—few crops are available everywhere all the time—and it doesn’t come cheap. . . . The real problem with his prescriptions isn’t economic elitism but produce xenophobia. The locavore ideal is a world without trade, not only beyond national borders but even from the next state: no Florida oranges in Colorado or California grapes in New Mexico, no Vidalia onions in New York or summer spinach in Georgia. Fully realized, that ideal would eliminate one of the great culinary advances of the past half century.”
