Here is another way of simplifying everything that has already been said.
Links-type conditions of the fast and firm firm variety simply add more golf course to every shot. Golf courses, especially good ones, have important undulations and hazards en route to the hole. Links-type conditions put these features directly in play and in turn, "add more golf course." Soft conditions, however, make these features null, and for a given single shot A to B (the hole), totally irrelevant. (They can be somewhat more relevant as varying the stance and distance to point B, but it is still a direct aerial shot to the hole. With soft parkland conditions, you might only have to think about 10%, or more often less (Tour pros: <1%), of the shot distance. With links-type conditions, one can have to interact with up to 100% (putter) of the shot distance. That to me is far more interesting and challenging and what will get me to choose playing most modest links courses over most top-rated parkland courses.
Also, I do believe from my experience and studies that links-type conditions can be achieved, or at least maximized, nearly anywhere given cooperation with the weather (that's a big if though in most places, understandably). However, I have not seen anything that can match the sparse, tight turf of the older links of Scotland.
