So, back to why the U.S. Constitution does not list the right to shelter, sleep or food. The Bill of Rights is not a document for Humans to follow. It was created by Humans for the Government to follow. People forget this all the time. At the time it was created there was no need to make a list at all because everyone understood what the Common Law was and already knew they had all their rights. It was greatly argued at the time of it's writing that no Bill of Rights should be included at all because to write the rights down is to create a list of things allowed (smacks of International Law), and it's limiting as a Human has rights that are infinite in their capacity to be creative without doing harm. So, when they finally did agree on a list, it was those rights they felt were so important that the Government itself needed to be constructed around them, so as to grant them to the employees of the government, because after all, they are human too. However, the government's capacity to act needed to be limited, and so the Bill of Rights is a limited list of rights allowed to Gov employees. It does not apply to ordinary people. And so, although a government employee still has the right to speak and carry arms, they do not have the right to privacy, or to own private business while in office.
