Why is it always recommended that you painting something, waiting for it to dry, paint again, repeat repeat, instead of just doing it once and add enough paint on the first go?

it depends on the paint, and the texture/type of wall you’re painting. adding enough paint to cover all areas might end up with a heavy streaky look. you want to use the least amount of paint to cover the area, but water based paint can also have problems of not adhering well to the wall (that’s why they say to clean the wall first, but no one really does that unless it’s obviously dirty). so if this happens, then when it dries, you either have heavy streaks or patches leaking through from the previous color. so having a second coat will fill in the gaps. there are brands of paint that advertise one coat, and they more or less work to a certain degree.
