It makes sense economically, but at some point you have to draw a line. Should I be taxed when I cook a meal for myself, because it&#x27;s a valuable service that would cost $X if I had somebody do it for me? Should I be taxed based on the price of transportation if I walk somewhere? Breathing?<p>It seems that we typically draw the line at the individual or household. If not there, then where should it go?
