“You cited an act that is common in commerce”
Obviously I meant digging a hole and refilling it for the purpose of digging a hole and refilling it. Like I said, it is not mine and a famous example. But also obviously you do not study economics so I guess I have to be as explicit as possible.
Replace digging with any pointless activity you can think of. Surely you must admit there is some work that bears no fruit. When you hit upon it, finish the argument yourself.
It was a typical retort of one that knows he has lost the debate. None of your comments has any relation to economics; you were simply attempting to refute an obvious truism with childish rhetoric.
