Simplistic or not, I think the analogy serves its purpose very well (thank you for sharing it). As I was reading the GP post the analogy I was thinking of was spraying weed-killer indiscriminately everywhere and naively thinking it would only take out the 'bad-guys'.

Doing it properly does involve understanding both what 'weed' means to you and 'desirable plant' then being careful not to poison the latter (and actually encourage it) while you try to deal with the former.
