The US has a three-tiered judiciary that moves slowly, Congress has a very high threshold for impeachment and removal (and a slow process), and the order of succession is basically locked in for four years. The people are not easily moved to action, and it's doubtful how much they could realistically accomplish.
Universal injunctions were a Band-Aid fix, one of the very few avenues our system permitted for there to be any rapid institutional response to illegal and immediately harmful policy. But that is no more.
As an exercise, what happens if a president issues a "throw enemies in the woodchipper" executive order? How many hours or days would it take the other branches of government to legally nullify the order? (What they can do in practice is another question.)
It's an extreme example, but a future admin could use the current admin's reasoning to unilaterally confiscate guns and force you to be a plaintiff in federal court to get relief.
