The Constitution is the document for that newly-formed government to protect those rights and to put the force of law to it...

Demonstrably false. The Declaration of Independence was passed by the Third Continental Congress, and the government of the congress was the Articles of Confederation. That government was overthrown by the Constitutuinal Convention with the state governments, about a dozen years after the Declaration.
