This language just fascinates me.
Yet it is true, a language develops by what its people and culture need to express. If you do not need to describe large quantities or be specific to make daily life work, then numbers are not necessary. This is exactly why the inuit language has multiple words for snow — because the difference between fluffy snow and slushy snow is a prevalent part of life. Interestingly enough, they also have the word iktsuarpok, which means to go outside to check if anyone is coming. There are no windows in igloos, after all!
