One could argue the same thing with clerics. What do they have to do to get their spells? Not much. The same is true for many other such rules. This is the sort of thing that D&D never codifies and just leaves to the people at the table (for better or for worse).
Yup. Pre-4E does require certain behaviours for clerics (and paladins, druids, monks, etc.), but I never really found it that interesting.
