The main reason is that anime is more about things like exciting battles, deep emotions, and interesting characters. For instance, in 'Fullmetal Alchemist', the story focuses on the two brothers' journey to regain their bodies. There's no room for such a strange topic as the one mentioned. Also, anime producers want to promote positive values rather than something so off - putting.
Well, generally, anime doesn't really center around such a strange topic as 'anime girl pooping stories'. Anime creators are more interested in creating stories about heroism, like in 'One Piece' where the characters are on a grand adventure to find the One Piece treasure, or about love and friendship in animes like 'Your Lie in April'.
Anime audiences expect stories about things like epic battles, character development, and interesting relationships. A story about an anime girl pooping is just not in the realm of what people look for in anime. It doesn't have the elements of excitement, inspiration, or emotional connection that most anime stories strive to achieve. So, it's not popular and is rarely even considered as a potential story concept.
Anime usually focuses on more positive and exciting aspects such as adventure, friendship, and growth, rather than such unappealing topics as 'anime girl pooping stories'. So, there are very few, if any, real interesting stories of this kind in the mainstream anime world.
