The bar rules you link to would heavily favor better players, therefore they would discourage beginners from picking up the sport.
And yet, those, with minor regional variations (most often call shot vs call details) are exactly what the vast majority of casual bar players learn, and play their entire lives.
People start to play pool, or golf, or tennis, or whatever, because someone introduced them to the game and they enjoyed it. Not because they approve of the rules that they are taught. In golf and pool particularly, most casual players simply play by whatever set of rules they were taught or that they mutually agree upon amongst their buddies, and leave it at that...
