Fair critique — AngelList is pretty aggressive with its fees. If you're willing to handle settlement + custody yourself, it's much cheaper. The oracle problem is very real (and solvable). Even ignoring the ability to transact within the same system where provenance is maintained, I tend to think that trusted third-parties moving their supply chain operations into a public ledger which is verifiable across time is more advantageous than point-in-time cryptographic signatures.
