I agree about what you write.. Also please note that I am not saying unsafe blocks are a bad idea. In fact, I think they are a great idea. But note that people run around saying "it is sufficient to audit unsafe blocks" but they really should say "audit unsafe and carefully analyze all logic elsewhere that may lead to a violation of their assumptions". You could argue "this is what they mean", but IMHO it is not quite the same thing and part of the usual exaggeration of the benefit of Rust safety, which I believe to be dangerously naive.
