My response would be that a studied appreciation of golf course architecture makes you a better player and, in many cases, makes it easier to "keep it in play."
I was fascinated by GCA from the time I was very young, but never pursued it as a career. Nonetheless, I learned from playing in high school that my interest had benefits for my actual game. I was among the best players at my school but we were in a league with some of the best schools in the state--as a result I was consistently paired in tournaments with players who were, objectively, far better than me. They could hit it farther, spine it more, etc. And yet I consistently held my own playing against many of them. The reason was simple. As befits a teenage male, most of them pulled out driver on every hole and ripped it--only if they were very familiar with a course would strategy off the tee be an idea. It became almost a joke how I was 20 yards shorter with driver than some of them, and yet wouldn't even hit that club off many tees.
Ultimately, execution is paramount, of course. Knowing the best place to be does not guarantee that the player can get his ball there. But you have a better shot if you (a) do understand the best angles and (b) match that to the best of your own abilities.
