You don't engage in interstate commerce on a day to day basis? Do you only eat food grown in your own state, sold by local businesses who don't operate in any other state?
So what? People who live in the EU engage in inter-state (-nation, I mean, to disambiguate) commerce daily as well, and that seems to be going no worse over there than it is over here.
I don't really see your point. Practically speaking, I only food sold in my local grocery store. Sure the grocery chain probably really does take deliveries directly from other states every day, but I'm not directly involved in the interstate portion of the supply chain.
