Nice weaselly sidestep - the point is that your attitude that the fedgov should DO SOMETHING about California medical marijuana, even though there no commerce nor interstate movement involved, is directly akin to the same torturous logic we saw in the New Deal-era Wickard decision - and in the mindset of those who just had the fedgov usurp powers rather than gain them through amending the Constitution.
All Congress has to do is "find" a "substantial effect on interstate commerce" and suddenly an Enumerated Power materializes. It's MAGIC!
