Though well-written and inspirational, I believe this post fundamentally misunderstands Ethereum and blockchains. 

Ethereum's distinctive property is objective, strict global consensus, and absolutely nothing else. It's great for usecases that require strict global consensus, but it's impossible for everything else, because Ethereum cannot parse any subjectivity or rough consensus at all. 

As such, while money, contracts, governance, identity, law are presented as examples, Ethereum can only parse very, very limited forms of the above, where it's objective. In some cases, like governance or law, it's almost entirely subjective with negligible scope for Ethereum to help. 

99.99% of economics, institutions and the like are deeply human and subjective, which Ethereum or blockchains in general cannot interpret at all. Indeed, we've seen many a times how forcing subjectivity into objective code has led to many disastrous outcomes in crypto.

Though it strings together then repeats words that aren't often seen together, this post fundamentally misses the most important property of Ethereum: Mutually Reinforced Conditions
