If these were the actual concerns, you can start the discussion at jurisdiction. Starting the debates with costs, though, sorta belies that concern?

Then, a problem you are going to run headlong into is that there are plenty of things that you can argue should not be done at different levels, but that are effectively controlled at a larger level. As a fun example, who makes sure that turmeric coming into the US doesn't have too much lead? Why can't/don't we leave that up to the individual states to fully deal with? Probably more fun, what about state laws that cover how much space is required for live stock for shelved products?
