Beside all the talk about labor, time, energy and so on. I think where forgetting if you had a Replicator you could make money that would me impossible to tell it was counterfeit money. That would surely screw up the economic system. Not to mention the replicator inself. Besides people do things all the time for thing other then money. Have you ever heard of open source software & not-for-profit organization. Sure they get money from donation. But there not soly doing it for the money. Beside there was a time when human lived without money. We usto organize to survive. Not by cutting off eachothers head. Otherwise we would have died out thousands of years ago.
