Correct me if I'm wrong, but the guaranteed rights (constitutionally) simply say the Government cannot do X, Y or Z. But the Government can do literally anything else.
The US Constitution say, fundamentally, the Government can only do A, B and C, and cannot step outside of those bounds.
Limitations in my meaning are not simply prohibitions, but functional limitations.
A set of limited, enumerated powers. Not all powerful as long as it does not do X, Y or Z.
This is subtle, but fundamental and, as far as I'm aware, quite unique.
