It is because the game is about points. It takes into account the players' likelihood to shoot 2-pointers, 3-pointers, and (I assume) the likelihood that they will be aggressive enough to get free throws. Basically, it is a direct look into how effective the game engine says your players were in that specific game based on tactics chosen, the quality of opposing defense, etc.
It does not mean if he shot 100 times, he would score that many points. It means that if he shoots a set of 100 shots MANY times, the AVERAGE of all those points scored sets would be the statistic. There is an important distinction; one is a meaningless statistic (as you elegantly pointed out) and one tells you how effective that player was.
They chose 100 shots for the same reason that ESPN or your local sports channel include points per 100 possessions; it gives a number that is typically more relevant than points per individual shot. It is the same statistic, they just scale it so it is out of 100 rather than 1. It also indicates that it is a predictive measurement, not a measured statistic. Which even with it being out of 100, some people still miss this.
Personally, I like this statistic a lot. I switch up the offensive style I play frequently, and the most effective lineups for each play style are not always what I would intuitively think based on their individual ratings. I want my scorers getting the ball where they are most effective; depending on the offense, I want my good-scoring, poor passing G in either SG or SF spot. Otherwise he tries to pass too much, gets stuck with the ball cuz he sucks, shoots bad shots, and his pp100 shots goes down.
