I'm not sure how to answer that.
A just-state answer is that Presidents do and will, as they are obliged to, and the Supreme court checks that they use their office in keeping with this Bill of Rights. But I believe this answer to be out of scope.
I suppose I can say important people desire more federal power than allowed by the Bill of Rights (which was put in place, of course, following experience with the British government). But that ads little, it's mostly a restatement of the assertion in your question.
When I was in school, they taught me the Constitution was a living document, and could stretch and grow to meet current needs. I accepted it as children do, but now I can say if you expand the tolerances of something sufficiently, you can effectively void a specification.
