Practically every product we buy needs to be assembled in order to be operational. Very few of the “things” that make our lives possible and/or enjoyable are simply born. I’m not talking about our families and friends, or even the household pets. (“Assembly” of living things is beyond the scope of this discussion.)
Sure, an argument could be made for the produce aisle. But even if we take genetically modified food out of the equation, those potatoes didn’t magically appear on the supermarket shelf or even at the farmer’s market. They had to be planted, cultivated, picked, and transported. All of those steps require equipment—and most of those “things” had to be assembled, one way or another.
