While there may not be a problem in this case, and I'm actually quite supportive of the proposed addition of the wikidata tags, I'm not convinced that this argument is completely correct. Take UK postcodes for example. Suppose that postcodes themselves are non-copyrightable identifiers, but their locations are subject to database rights. Suppose we have a copyrighted database of each address with it's location and postcode. For each address we could search OSM for objects that may represent houses/businesses in the vicinity of the location in the database. In cases where there is exactly one match within say 10m of the location, we could safely assume that the postcode belongs on that object. Suppose we automatically add the postcodes to these objects. We arguably haven't added any copyrighted data to OSM, and certainly haven't added any coordinates from the copyrighted database. But what we'd end up with in OSM is a list of postcoded objects with OSM coordinates that are pretty much the same (within 10m anyway) as those in the original database. It seems to me that the owner of the postcode database would have cause to complain that the OSM data is a derived work of their database. The use case for wikidata is slightly different, since (as I understand it) the location data is being used more as a filter than as a primary matching tool. But I think we may need to be a bit more careful. Perhaps LWG should be asked for their opinion...
