It is almost like 99.999% of the crypto people don't have computer engineering or computer science degrees or have never built a production system that requires concurrency and fault tolerance over a persistence layer. A system that validates new entries into a database can either be "very cheap and very fast" or "very fault tolerant and very decentralized". The speed of light in networking and the speed of modern CPUs make this unavoidable.
