You're ignoring that the law states that the Commandments are “foundational documents of our state and national government.”
As you may be aware, it was very important to the Founders that people have no other gods and not make graven images. The U.S. Constitution specifically forbids taking the Lord's name in vain. And of course, it is required to keep the Sabbath holy.
No coveting, either, whether it be houses, wives, or animals. Those are right out.
