With a replicator there's no need for money.
The basic function of money is to serve as a substititute for trade. If you can replicate stuff the stuff you need (foot and shelter basically) you don't need to trade anymore and therefore don't need money.
I'm not saying that people would stop trading. I think that people will still seek status and therefore status symbols. But if you could replicate all the basic stuff then the whole thinking of I have to work a day/a month/a decade to work for something goes away. You just create it out of thin air (more or less). So you can't judge stuff by their monetary value anymore, because there's nothing to base it on.
