Look, I don't know why you have such piss-poor critical thinking skills and a complete lack of any ability to read the voluminous coverage on the subject.
But the entire reason Trump wanted this ruling was because it would make it easier to trample people's rights. Without national injunctions, your rights do not exist. This is especially true for immigration. The Trump admin is also fighting to be able to deport people without due process, and you're already not entitled to representation during immigration procedures.
What portion of immigrants can afford a lawyer? If you're a low-income US citizen, and Trump decides to revoke your citizenship, what exactly is your plan? Yes, you have citizenship from birth, but that doesn't matter. Trump has decided to just fucking ignore the Constitution entirely. And yes, in theory, you can sue the admin in court, but good luck with that. If you can even afford a lawyer, by the time you find one, you'll already be on a plane to Sudan.
How are you so dense that you can't realize that the entire point of Trump pursuing this is that he wants to remove from people the ability to challenge his illegal actions? There's literally no other reason to do this. If you live in the US, you have seen your own rights massively curtailed by this ruling. But you're either too stupid to realize that, or you're just happy that you're not likely to be at the front of the line of people being fed into the meat grinder.
Don't link to a massive ruling and tell people "just read it" you fucking goober.
