The central bank can print money without bound. Some of the effects of money printing changes with confidence in the currency, but the core effects that it targets don't really change until people radically change behavior to reduce use of the currency as a medium or even measuring stick for routine transactions.

Anyway, this isn't relevant to my argument upstream — it just changes the reason why nuclear reactors aren't properly pricable in our market economy, from "can't be insured due to worst case" to "worst case can destroy the currency". (It also doesn't rule out other argumens, pro or contra.)
