A small victory but a victory none the less

The Supreme Court handed down a ruling reversing a lower court's injunction blocking President Trump from using $2.5 billion in military funding to build the wall.
Technically They are only replacing existing wall, but that "wall" is in many cases little more than an imposition for vehicles and does nothing to slow foot traffic.
I have yet to see the actual ruling, but what should have happened is a multi-pronged approach. The court should have struck it on grounds that the district in which it was filed contains ZERO border wall construction. it's not even in California.
The second part should have addressed that the President has wide discretion to use military funding in the protection of U.S. citizens, and part of that protection is stemming the flow of illegal drugs from Mexico, and the violence which accompanies it.
The third part should have addressed who can file complaints of that nature, and where they can be filed. In my opinion, something like that could be filed by a joint resolution of Congress, but not by any individual person or group, and certainly not by the Sierra Club. As I remember, they joined with the Alien and Criminals Litigation Usurpation in this fiasco.
