I think the problem is that we count value in money terms. If I work as a writer and earn 100 USD I can spend them on a new hair cut. The barber will be able to spend it on reading articles I as a writer writes. This can go on forever. This probably is real value for both of us.

However, if I am a producing sting shit from shit and I use an advertising company to make people believe that shit is the shit to have and people buy my shit... in money terms this is maybe the same value but is this value?
