Well sanitation workers make up a fairly large fraction of the minimum wage workers so that's a representative group of people for the matter at hand. You're not wrong that unnecessary private exchanges like that might be lost, but those are unnecessary, not that noteworthy in terms of economic scale, and generally aren't relevant to minimum wage laws anyway. My point is precisely that most of the labor that is priced at minimum wage is not like the example you describe.
