1. The executive is doing something illegal to hundreds of thousands of people.
2. Dozens and hundreds of people sue them.
3. The executive loses in court.
4. The executive does not appeal to the supreme court the cases it lost.
5. Thus, no binding precedent that stops the illegal action in #1 is set.
This is actual lawless lunacy, and this enshrines it as SOP going forward. Is this the country you want to live in? Do you think this is how it should run?
Here's a wild idea. If the executive disagrees with the federal courts on the merits of whether or not its decisions are illegal, it can appeal up to SCOTUS, and win a case on its merits. It can't do that because even under this SCOTUS, their case has no merits.

That is the entire bloody point of checks and balances. You are cheer-leading the complete destruction of them. The government, when challenged on the legality of what its doing, needs to win their case in court, because the courts are the final arbiters of written law.
