What this part means
only bounded once you have already imagined the worst plausible use of the capability — the same failure of imagination that undermines defense-in-depth probability estimates generally.
Its job in the formula

Where the article explains it
An estimate of assumes a threat model that has to guess at an adversary’s behaviour, and is only bounded once you have already imagined the worst plausible use of the capability — the same failure of imagination that undermines defense-in-depth probability estimates generally.
The passage around this formula
There is a simple way to see why capability removal should be the default move rather than the fallback. Model the expected exposure created by a credential as a sum over the capabilities c it carries, each with some probability that it is exploited in a given period and some damage if it is:
