You are assuming that the set of OSI- and FSF-approved licenses will never change. That is an unwarranted assumption. Entirely new free licenses might appear, new versions of existing non-free licenses might become free, and new versions of existing free licenses might become non-free. The future is unpredictable, and licenses can evolve in strange directions.
