There's also a few places I roll my eyes but I sort of have to suspend my disbelief. The premise that everything is being super paranoid, but at the same time, not insisting on spinning up their own node, for instance. Or putting the key into a computer without specifying an airgap.
Thinking about how that'd flow as an audiodrama though, I can't blame y'all for the choices made. I don't envy the task of trying to make this accessible for normies but also comprehensive enough to cover the necessities.
