You are completely ignoring the primary motivation of both practices which is very much in attempting to understand yourself.
It's a shame when those who decry alternative systems do so using flawed logic.
What I am trying to say is that most people will not dig further and most importantly will not even try to put some honest work in trying to understand things in order to try to repair these.
And assuming I am right, Astrology is not really helping much, because if you are "stubborn because you are a Taurus or whatever" what are you supposed to do? What kind of corrective practices will Astrology suggest?
Please enlighten me (I am not sarcastic): in all my dealings with people who were interested in Astrology (interested beyond the most superficial interest) everybody was trying to "understand", a minority was trying to "predict". But nobody had any Astrology-based best practice to "heal" or "repair".
