Why do electrical charges in any object gather at points?
(The highschool textbooks say it does, but they don't say why...)

What is inside a containment is a number of charges.
A charge represents electrical energy..
So no matter how much electrical energy exists in the containment it can be considered one lump as a point at the center of the containment. This is called Gauss law.

This is an 'old wife's' tale. They do no such thing.
However...
1. It is mathematically convenient to talk of point charges. This allows us to ignore their physical size and in most cases their size is insignificant.
2. A spark is said to leave a sharp point of an object since it was the closest point to a surface with a lower/higher potential difference.
