I agree. But it is no where stated or implied that this should be an unlimited power. In fact, clear limits are placed upon that authority.
If I invent a cypher and store all of my physical written works using that cypher, can the government compel me to decrypt those works upon discovery that they lack the ability to do so? What if I taught that cypher to my family? Can they be compelled? If so, under what authority?
>You might just as productively suggest that we can't trust the USG to be a responsible state
This suggestion is inherent within the Constitution. It is framed upon a mistrust of any Government to not become tyrannical.
>therefore it should disband
uh, what? nice leap.. did you use rocket shoes to get over the gap?
