Lol... way to both miss the point of why we enjoy only a broad overview of skills and be both condescending and insulting at the same time. Here let me reply by using your post but addressing your viewpoint...
In the end though, this is true, and it's exactly what some/many people want. Some DMs can't make a decision without the book to back them up and provide affirmation of their choice, they feel like if the decision is in a book it cannot be wrong or bad, and the rulebooks back that up. Some, especially those who game exclusively with strangers, really like the idea of "the book as DM" because it's hard to facilitate communication with everyone siting around the table. Some just worship the system as the end all and be all and just want to have fun with what basically amounts to a bunch of if/then statements in the form of a tabletop rpg.... fun; with fewer demands on actual decision making and fiddly, esoteric character creation rules, game X fits that. So yeah, a system that tries to cover minutae to the point of becoming burdensome and bordering on work instead of fun along with a DM who is like "Uh, da book will tell me what to pick"" works in those regards...
How did I miss the point, exactly? Sorry you were insulted...I have no idea why you would have been. You weren't even addressed; I was addressing the way the system was laid out. Did you write it? I also pointed out that people like it the way it is...how is that insulting? No offense, but I think you're being really sensitive; there's nothing I wrote to get insulted about, truly.
I know you didn't understand my point...it's not that a DM can't make a decision without guidance, it's that guidance from the designers of the game would be nice to have. No one has asked for the book as DM, merely the book as guide...like the title of the book reads.
