If officers of the Executive branch can ignore a judge's order without repercussion, what would keep them from doing the same to me?

There's no indication - yet - that they can ignore a judge's order without repercussion. In all the instances where they've gotten up to no good, they've always had a fig leaf of a legal or factual argument that they asserted. They may have tried in many cases to thwart the intent of the order with the most strained arguments or interpretation - but they've always left themselves an escape hatch to at least claim they weren't just ignoring it. Because they know that they can't cross that line.

And the federal judiciary is noticing, which is one reason (IMHO) why the Administration is doing poorly in court. Partially because their arguments are weak, but also because they're generating a track record of playing way too cute with edging up to the line of deceiving/defying the judiciary. I think the Administration gets more than just two votes on the Alien Enemies Act decision in SCOTUS if they had been playing straight with lower court judges and not rushing to create irreversible facts on the ground.
