If latinum is just the worthless medium onto which wealth is written (like the paper on which bills are printed), then replicating it would be useless, as the actual wealth is put into the material by other means. Say, each brick could carry a chemical code, but the presence of the code would not be relevant - the content of the code would. Replicate a given brick, and you have now two bricks with identical codes - meaning one of them is worthless because there's only value worth one code in the economic system (just like there's only value worth one 100-dollar bill with the serial number ABC1234567, and any duplicates are identifiable as worthless). And since it's impossible to tell which one of them is worthless, both are...
Only bricks and the like would be subjected to serial number scrutiny, of course. With mere strips, one wouldn't bother: a genuine-tasting strip is good enough, and can be further circulated because nobody else will bother to doubt its value, either.
