Seems to me that the article starts with an argument that Puerto Rico’s addresses are confusing to US addressing because they follow Spanish heritage. And then argues that replacing with Geocoding would lose the heritage connection. Presumably making addresses US standard would lose the same heritage connections. Also seems to fail to recognise that the zip code or postal code part of the address is a specialised, possibly irregular shape, geocode that identifies an area of the world within its local context.
