The Constitution does not grant or declare "Life, Liberty and the pursuit of Happiness" that comes from the Unanimous Declaration of the thirteen united States of Amercia. The primary function of the Constitution is to regulate Government between the States through a central system- personal liberty has little to do with document as originally written and understood, much of the Bill of Rights was, for years, only related to the acts of U.S. Government not the States- the Federal Courts, over time changed this. Each State guaranteed personal freedoms and rights with their Constitutions or with declaration of rights.
The States collectively, as a Union, own the power of the U.S. Constitution- they formulated, accepted and modified it. U.S. Constitution does not have power without the consent of the Union of States. The States can abolish it, they can write another, without any interference of the Federal Government in which THEY created. The freedoms of Americans were ensured prior to the creation of the U.S. Constitution with the Declaration of Independence, and winning the War of Independence ending with the Treaty of Paris.
