Why Do So Many Women Nowadays Wear Nail Polish?

I am personally disgusted by nail polish, especially when it's what people would call "put together" or "clean". For this reason, it has always been surprising to me that so many women wear nail polish. It also seems like more women are wearing it than ever in the past.

I have a few theories:

1. Some women like the look (I've seen many women with an obsession with "toe beans" on animals, so nail polish kind of resembles them when your nails are highly contrasted with your hands);

2. It is used by women to present themselves as "clean" which can sometimes (but not necessarily always) be them overcompensating for otherwise being seen as dirty.

3. Many women are in competition with each other so the women that would otherwise not wear nail polish are now wearing it as a result of peer-pressure. Perhaps older women also pressure younger women too.

4. There are men who like it.

If you wear nail polish, why do you do it (feel free to elaborate in your answer)? And where on Earth are the women who refuse to wear nail polish?

For all of you claiming I am attacking people for expressing a different opinion:
1. In my question description, I am simply conveying information in a concise manner with the relevant details; if you find that offensive, then you are too soft.
2. Look at the responses to my question: people are telling me to "grow up" , calling me "pathetic" or simply laughing at my question rather than giving me an answer to my question. So who is the one starting the attack? Not me. Call that person out.
