The US president (or other authorities) can't just make new laws out of thin air, that whole democracy thing gets in the way. Short of rolling tanks down the streets of cities and towns everywhere you're not going to be able to enforce much. Even then, with tanks on the streets you have a very very bad situation on your hands. People in the US don't like having liberties taken away without due process and representation. And by "don't like" i mean will fight to the death over it. Edit: also the federal government can't just "demand" things of the states. That whole republic thing gets in the way there.
