The question is can you really make it simultaneously cheap to trade and decentralized and always on. Or is the overhead of all that just make blockchain tech very awkward and suboptimal (especially since ultimately there's a centralized winery that honors the "claim" with actual wine - so no real need for decentralization). Instead why not just have a little centralized company that lets companies create ledgers of asset ownership for $300/month. If it's a real use case, any winery can sign up, etc.

Issue is blockchain tech doesn't actually solve anything
