IMHO, 3(.5)e D&D is a game of modularity - being able to apply the same items for one character to another - and Dragonmarks were designed to be modular as well to give the players (and DM) more control over how critical an aspect of their character the dragonmark is.
Relegating a particular dragonmark to an NPC only thing would cause two problems. 1) It presents restrictions, not choices. 2) It'll cause unnecessary asking of the question, "Well, if this is how these three houses work, how do the others?"
D&D tries to provide you choices. All of them have value in specific situations. The idea of balance in D&D is that nothing is "must have," but your "must haves" are determined by character development.
