You realize that this is exactly how it works with locked crypto systems normally right?

If the system is designed better there isn't even an apple to cry to to demand it be unlocked because they don't possess the key nor the means to get at it.

This is not nearly so huge an impediment as you might imagine. A computer that you couldn't unlock for love nor money when its off and cold could be attacked and accessed beforehand and most people leave a multitude of electronic evidence behind outside of their own machine.
