Because you can win awards, pad a college application, and qualify for scholarships with any one of the other activities I already mentioned.
Hopefully the main benefit is that they enjoy the activity.

I am separating this last part of Dude's statement because so many people have this incorrect perception.

In addition, most college admissions officers prefer well-rounded applicants.
Selective colleges are NOT looking for well-rounded applicants. They are looking for a well-rounded CLASS. They can put together a well-rounded class by getting the star athletes, the champion debater, the musical prodigy, the politicians, accomplished actors, and yes, even the math and chess prodigies.

Some very specific examples:

* My nephew, who graduated from Yale a few years ago had the 4.0GPA & 2400 SAT (one sitting) and had done some science research with a professor while in high school. His words were "Yale doesn't want well-rounded people. They want pointy people!"
* My next door neighbor has a daughter who is a math prodigy. She is finishing or has finished her PhD in Harvard.
* Two doors down, their son was high school President and near the top of his class, and was accepted into Cornell.
* D's best friend's older sister is now in Harvard. She was a state champion debater.
* My boss has two children in HYPSM. One child was state-level competitive in both debate and track. The other was exceptional in math.
