Everybody has said it in a correct, yet different way, but here's another:
The value of "straightness, straight-line, center-point accuracy" is what a "target golf" hole/course demands...think archery or a firearms course, where there is a bulls-eye...the farther from the center one is, the worse the performance.
This is most often thought of on green approaches. but it means something to tee shots as well. It is commonly associated with penal and confining design, where the punishment for an un-centered hit, can be woods or OB or water or sand...on both sides of that "centered" target. There is little tacking to one side or trying to allow for the best place to miss, if it's not in the center, it's no good.
When I think of "target golf," I think of TPC Sawgrass (as an interesting thought provoking, oft-heroic example) and the original Trump National course in Briarcliff Manor (as a desultory, unfriendly, penal example).
In target golf, most often you hit it where the architect has directed, on each successive shot... or you need a hot putter.
