Cool! I totally see why this is relevant. I had to work with this pyramid as well when I went to school for social work. I think maybe that esteem and love are backwards because it is just human nature. Think of when we are babies. A baby has to seek approval from his/her primary caregiver in order to feel safe and confident in exploring his/her surroundings. Love is a foundation to the rest. Once that foundation is set, we can explore achievements, mastering things such as school or in hobbies or at work, or becoming independent (like the child). If I remember correctly, some of my professors suggested that "love" was also self love. That could be the discrepancy ;-)
