How? Food and trade are national issues. A state cannot set regulations for how food is grown or produced in other states and countries.

Do you expect states like Mississippi, which can barely fund their own schools, to also fund expansive regulatory agencies?

Also, why should there be 50 different sets of regulations on the same product sold in the same country? That's ridiculous.
