I don't personally think there's much of an analogy to be offered between body hair removal and clothing. There are numerous practical reasons for wearing clothing up to and including legal prohibitions against not wearing such. Hair removal is a purely aesthetic concern, a fashion trend. Given that women are more profoundly connected in terms of their overall social identity to such fashions it follows that when they happen they tend to be regarded with considerable seriousness. i.e. where some social memes are concerned, a particular behavior may be seen as necessary for a female to be perceived as behaving in a womanly fashion (rather than just being fashionable, if you get the difference). These particular trends, whist in reality having no more intellectual or ethical substance than any other trivial aspect of fashion, are powerful social forces, and ones that I find deeply disturbing. I believe women in those western nations (or elsewhere) that still cling to this especially banal meme ought openly defy it, if only to express the fact they are a conscious, rational beings who won't be told by thoughtless herd animals what it means to be a woman.
