They may have the power to regulate commerce, but my personal garden is not a commercial enterprise and certainly not interstate. Therefore, none of their concern.
Let me ask you. Do you believe that Congress does not have that power? And what is it, exactly, that makes you believe this?
Oh, I believe they have the physical power. I do not believe that the Constitution grants them the power to regulate what I grow in my backyard garden. I do not believe that the founders intended them to have that power. In a country that was created celebrating the individual rights and freedoms, a fedgov with that kind of power is non-sensical.
It is certainly conceivable that your garden and 50 million more like it could affect the interstate commerce of produce. Whatever you produce, that is the less you buy.
So, if everybody grew their own tomatoes, that wouldn't affect the existing interstate commerce of tomatoes? And if Congress is regulating that commerce for the good of the nation, you should be allowed to undermine and subvert that nationwide effort?
What a selfish individualist you are.
