There are only 8 interstate crossings and less than a 100 crossings of 2 lane roads. People moving across the boarder is not a huge concern. We are in the second stage of Foundation conquest, and commerce is the arbiter of civilization. Cut off commerce and you have, well - just look at Cuba.
Besides, it’s not just the commerce. Block off regular transportation and revoke citizenship, and everyone left of semi-liberal in TX will leave - and with them most of the knowledge worker/white collar worker base. That’s would do more to decimate the TX economy than any other pressure.
