More than we can know right now BUT this could be a very smart play.
Start building the rest of the wall with a vengeance.
Feds demand the work is to be stopped.
Abbott immediately and very publicly announces he will NOT stop finishing the wall and also announces additional crews are being added to speed up the process.
Have DPS and Texas Rangers ready to move and arrest any Feds showing up at the border in an attempt to stop the work.
Contract with professional private videographers to embed with DPS and Texas Rangers to document the arrests and preserve that documentation. This makes the documentation the property of the State of Texas
Hold the Feds, get them arraigned and set court dates before their release.
Hold the documentation and get the Feds to trial in the summer of 2022.

Yes. Almost any federal act requires the cooperation of state governments to enforce. All states have to do is just stop cooperating and even arrest any federal workers who violate any 10th amendment boundaries in question. Every state is supposed to be almost an independent country. We were never supposed to be one monolithic mega-nation with 50 subordinate provinces.
