The critique being made in the original article, I think, is that it's extremely hard to find a hypothetical use case for blockchain technology that can't be done without blockchain technology. A wine exchange seems to pretty clearly fall into the "things we can do pretty well without crypto" category, so one needs to explain what crypto is bringing to the party that makes it a marked improvement. In this particular example, both "trustlessness" and "decentralization" are off the table (e.g., there is only one winery and you are trusting them to hold the physical goods).
