Your friend's site and this article suffer the same basic problem: blockchain technology is really only effective at solving these problems: 1. Timestamp validity is of utmost importance (proof-of-existence). 2. Transactions are being heavily censored and there is a need for truly peer-to-peer value transfer. This article has a terrible introduction that explains blockchain as enabling an upside-down communication method allowing users to aggregate their requests among many apps. This isn't something that a blockchain is needed for. In fact, I'm finding it hard to see how a blockchain improves upon traditional solutions already implemented. Also, as you said Afton, traditional contracts work just fine and are preferable to blockchain contracts in almost every real-world scenario. In the case of agriledger specifically, I am wondering why ECDSA concepts aren't enough to solve the problem of authenticity of records. Blockchain apps can really redefine many concepts and processes, just like Bitcoin's blockchain is redefining money right now. However, I'm hesitant to over-prescribe blockchain as a solution to all that ails the tech world.
