Realistically, the wet blanket for replicators would be copyright, patent, etc., laws, and anyone who thinks such laws are going away, ever, is dreaming. So while basic food and other generic products would be cheap (presumably the only cost would be the raw materials and energy), as soon as you try to replicate the latest must-have name-brand item, your friendly replicator will ask you which form of payment you prefer.
Also, can small replicators replicate large objects, such as a car, house, boat, etc.? If not, then that is a major wet blanket too, since the largest items also tend to be the most valuable items. Even if they can replicate large objects, you're going to need, literally, tons of raw material to feed it. Where are you going to get that? Your back yard? Not only is that a lot of labor (assuming you can't just beam it into the replicator; considering the massive destructive power of a beaming device, I doubt they'd be legal for Joe Citizen to own; it would be like letting citizens have nukes), but pretty soon, you won't have a back yard anymore. There's no such thing as raw material that's cheap by the ton; even something as common as dirt costs quite a bit if you want tons of it delivered to your house, and you know the price of dirt and other raw materials (which would be controlled by land owners) would go through the roof when it turns out that you can feed tons of it into a replicator and it will spit out e.g., a yacht.
