For argument sake, if good golf was all about perfect alignment, the game would be far easier. Of course basic alignment makes total sense....no argument. But beyond that, your brain and body will actually carry-out very basic rudimentary instructions without manipulation. For example, I can line-up to a shot in a neutral position, then "think" "hit a fade". More often than not, a fade occurs. I have no idea why because I don't try to line-up to hit a fade. I truly believe that's why the best players simply visualize their shot....it's a subliminal "road map" of execution instructions.
It's kinda like if I toss a set of keys to you, then say "toss them in the basket to my right, you'll probably hold the keys, not really think, and redirect your arm to toss the keys in, or very near the basket. You don't think "Ok, I've got these keys, they're in my right hand, the basket is 2.5 feet wide, and about 7 yards away". Nope. You hold the keys for a second and toss them, without really thinking. My point is I think we can over-instruct ourselves more often than not.
Your body will do amazing things but if you aren’t aligned correctly it is impossible to hit good shots consistently.
