From the Declaration of Independence, which doesn't have legal authority per se but is revered as one of the country's foundational documents together with the Constitution: >We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. Pursuit of happiness includes having the right to try running a business and making it successful. And from the Constitution, its preamble: >We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America. The establishment of justice, promoting the general welfare, and securing the blessings of liberty by the people for the people means the government cannot prohibit someone from running a business without following due process and citing due causes. And as a catch-all, from the Ninth Amendment: >The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
