Another way to say the same: there is no slack. Errors can be sudden and complete.
Compare with "old fashioned" contract law or e.g. national currencies or gold. The errors there (theft, counterfeit and fraud) tend to impact only one or a few transactions. It's all more localized/
In case of broader failure of old fashioned money (e.g. national currencies being destroyed through inflation): at least this is a very slow process that is usually being telegraphed years in advance.
