The NSA, of all people, are well aware of such a limitation—after all, it is the reason that Digital Restrictions Management doesn’t work.

Apparently NSA knows the reality better then you and they obviously knows that DRM does work. The governing principle in security is famous ages-old you can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time. DRM can not full fool all the people all the time - here you are absolutely correct, but it can fool all the people some of the time and this some of the time is growing: just 10 years ago DRM typically DRM was broken in weeks, often days, but today it takes years for well-designed DRM systems (XBox360, PS3, etc).

If you'll consider the fact that lifespan of typical phone model is 2-3 years... this means that for Android DRM may work just fine.
