Might it be sufficient to dynamically block anyone that has a registered home address in Mississippi for their payment method? Most ISP's span multiple states.
Google have additional information about IP addresses that updates dynamically based on cell phone, wifi and other magic usage so maybe ask them if they have some javascript that queries their site for more specific city/state details. Also call Pornhub and ask how they were blocking specific states to meet legal requirements.
