"a Star Trek type replicator would streamline that process by a fair margin and have far fewer critical links." Would it? We're never really shown how replicators work or much else about the logistics of the Federation but I've always assumed the support machinery and network behind the replicators must be pretty enormous. Not only the manufacture and maintenance of them but just ensuring all the energy, fuel and raw elements are available and can get from A to B would be complex.
