Inventing categories is what the court does. The Constitution is incredibly brief, and gives zero guidance on how to clarify conflicts. It has always been full of "common sense" exceptions, like criminalizing threats (despite the unqualified "freedom of speech" language) or probable cause (police can invade your house if they know you are committing a crime right now).
The sum total of these "common sense" exceptions, and the "legal reasoning" that extends them to the modern world, means that the document itself doesn't actually mean anything. Your rights, such as they are, consist of literally millions of pages of decisions, plus the oral tradition passed down in law schools.
