From the same wiki article: "The wine trade in Italy consisted of Rome's sale of wine abroad to settlements and provinces around the Mediterranean Sea, yet by the end of the 1st century AD, its exports had competition from the provinces, themselves exporters to Rome. The Roman market economy encouraged the provinces’ exports, enhancing supply and demand. An elevated supply of wine meant lower prices for consumers." If that's true, then it worked out well for Romans wine consumers, likely freeing them from local wine-making monopolies, and also for the development of regionally unique varieties of wine. Also, what is the relationship between Roman wine making technology and Teslas? It's not like China doesn't know how to make electric vehicles - they already produce many more that the US does.
