This is what pg said she said: "What she meant was that it's impossible to get that rich without doing something bad"

What you said she said: "The only way to get there is to set up a structure that extracts a billion dollars from a market"

Extracting does, in fact, imply "something bad". To extract is to take something for yourself without adding value. That is bad. Your language implies that the people who make that sort of money do not add, which is what pg is trying to refute.
