> To that end, I agree with your basic point: you need an interface to the outside word that has similar properties to the core model. At least, trustless, transparent, auditable. Probably anonymous as well.

Which is impossible because at some point the entire thing needs to interface with humans and human processes -- neither of which is infallible. The entire premise of Bitcoin, Ethereum and "Code Is Law" is broken at the core. They all try to get rid of "trust" by replacing it with computer code but at some point you need to interact with meatspace and meatspace is not logical, and not at all trustful.

In other words, trying to make everything trustless is futile because at the end of the day, you eventually have to trust other people.
