Silly, there would be no NRST on your used stuff.
Or suppose that I go out in the woods and spend a weekend cutting and splitting firewood, which I then sell to my neighbor?
Or suppose I design a house (or a software program) for a client?
It appears that the people advocating the NRST have never designed or built anything in their garages and studios, but have always depended on a paycheck from somebody else.
Cash will have to be banned for the NRST to work. But that's OK. We'll just come up with a black market currency to go with the huge black market that will spring up. They'll probably have to ban gold and silver coins as well...
