I can't provide specific evidence for you to sue the US Govt over NAFTA, but your comment > Commerce has to cross the border for what you are saying to be true

I can't provide specific evidence for you to sue the US Govt over NAFTA, but your comment > Commerce has to cross the border for what you are saying to be true. seems overly broad. I think there are established cases which disprove that. All it has to do is have an impact across the border, not necessarily trade across it. http://law2.umkc.edu/faculty/projects/ftrials/conlaw/statecommerce.htm http://law2.umkc.edu/faculty/projects/ftrials/conlaw/stateco... is full of interesting examples with Hunt v Washington State Apple Ass'n (1977) being one of many that seems relevant. And https://en.wikipedia.org/wiki/Gonzales_v._Raich https://en.wikipedia.org/wiki/Gonzales_v._Raich for an (arguably) purely domestic california marijuana law.
