I just played the Ocean Course at Kiawah and I would not agree with your statement as to that course. Many of the holes have huge landing areas for tee shots (2, 3, 4, 7, 9, 11, 12, 15 and 16 all are quite wide - although some of these narrow a good bit at the green).
There is a ton of strategy involved in the course. Many risk/reward tee shots. (2, 3, 6, 7, 10, 13, 15, 16 and 18) There are many shots where if your going to use driver you have to shape the shot or you risk rolling through the fairway -- the other option being to lay back with an iron and leave yourself a very long approach. I would consider these strategic decisions that have too be made several times on the course.
Many of the greens are set at angles to the fairway. So approaching from the wrong side of the fairway often means having to carry a very deep green side bunker or the marsh that would not have had to do if properly positioned.
I don't think anyone would describe The Ocean Course as easy (Slope 139, Rating 73.4, 6779 yards from where I played it). If your statement is true (and I'm not sure it is), then the Ocean Course is the exception.
Perhaps the mark of a truly good course is having width, strategy, options and angles, while still providing a challenge to most golfers.
