If the whole universe were black, you wouldn’t be able to tell objects apart. They’d all be a single black mass. Just the same, if a whole file is a mass of code without enough consistent, logical spacing, it’s hard to separate out the pieces. Space is what keeps things separate.
You don’t want too much space, because then it’s hard to tell how things are related. And you don’t want too little, because then it’s hard to tell that things are separate.
