Well of course, I myself see myself as acute, sharp and fine, 8-) but my own condition is entirely beside the point, except just now to illustrate how put-downs tend to provoke put-ups. But I repeat, personally, since you make it so, why should I care whether I am obtuse or acute, blunt or sharp, coarse or fine? How does this good feeling or bad feeling enable or prevent me from posting in whatever manner I post? — unenlightened
Note, I said
your response seemed obtuse, blunt, and coarse, (and surprisingly so) not that you are personally obtuse, blunt, or coarse.
As a concept, self-esteem is having its day. According to Google Ngram, the use of the term was flat and sparse between 1800 and 1940

Some people dislike the term--midwestern suburban political and religious conservatives, for instance. There was a very negative reaction when some state education departments added a self-esteem promoting component to the curriculum. I am not suggesting that you are part of that cohort. You have your own reasons for disliking the term/concept. (It is a guess, of course, that you dislike the term. Maybe you love it.)
Contemporary mental health thinking holds that it is a good thing if people think well of themselves, whether they are obtuse or acute, blunt or sharp, coarse or fine. (There are limits, however. The self-confidence, self-esteem, and auto-biographical praiseworthiness of a Donald Trump locates him in the category of puffed-up narcissist.)
Self esteem is part of a larger picture of what healthy personhood
can be. Self-confidence, self-assurance, self-respect, dignity, morale, self regard, self-satisfaction, and so on, are related terms. One word list has it that humility, modesty, and meekness are it's opposites, which is certainly debatable. Self-loathing, self-abnegation, and self-destruction are the well that one falls into when self-esteem runs out.
*** Here's an sample of how Google Ngram gets its information:
Phrenology: Or The Doctrine of the Mental Phenomena, Johann Gaspar Spurzheim - 1833.
"Organ of Self-esteem. Self-esteem is one of the faculties generally attributed to external circumstances ; but its activity is so very great and universal, that I am astonished it has not been at all times considered as a special feeling."
