Context matters here. This list is from Thinking In Systems and it simply presents a high level model for leverage points at which to intervene in a system. It doesn't specify any system in particular and the author notes that you have to intervene at the level that is both effective and possible. It's not as if the recommendation is "a paradigm shift is required".
