While the courts, supposedly, focus on what the law actually says, remember that Wickard v Filburn (1942) established that growing a plant on your own property for your own personal use is "interstate commerce".
I don't know a lot about law, but I at least know that ruling on what the "actual law is" is selective, and usually selective in a way that is beneficial for the rich and powerful.
