If you're going to pay the money, might as well take as many strokes as you can. Compared to a scratch golfer, a double bogey golfer gets ~50% more game for his money.
That's an excellent point, and we see the course from side to side instead of the boring view right up the middle. For me it was more a matter of etiquette: I rarely traveled with proper attire, and hacking up a championship course seemed disrespectful.
