The document discusses the progression of commerce from centralized to decentralized models, and how technology like the internet, blockchain, and Ethereum can further push trade towards decentralization. Specifically, it notes how early commerce was localized but is now conducted globally online through platforms like eBay, Amazon, Uber and AirBnB, which started as centralized matchmakers but their roles are becoming decentralized with many players. Ethereum aims to facilitate this by enabling trust and transactions without centralized intermediaries.
