I know I will get flamed but I'm ready.

Why does a family/couple/solo traveler/guest-of-any-sort need more than 3 fastpasses in a day? I find this to be incredibly greedy. In any given park, there are about 3 big attractions (give or take). Is it absolutely necessary to ride those 3 biggies over and over and over again with little wait? Hey - I get it. I love Disney too. But, seriously? Why is it undesirable to have to share? This thread is making me shake my head.
