Because the effort you are talking about is completely unnecessary. Imagine every grocery store would require you do a little dance when you buy a carton of milk. Your vision needs some narrowing (which I believe will justify the parent point), because as-is it has obvious counterexamples. I believe your problem is that "effort" is unspecified. "some effort" would make the statement correct, but some effort does not justify arbitrary effort, therefore you have no point here.
