Great! Let it be so. Even tying up ICE in court cases the states are sure to lose is a victory since it demonstrates a willingness to resist the Magestapo and puts a (temporary) break on their abuse of constitutional rights.

It's not going to "tie up ICE in court cases." The prosecutions would be handled by other parts of the DOJ. ICE will still be doing what they do. To say nothing of the fact that it's pretty unlikely the police would ever do this...because they know that they don't have a leg to stand on. It wouldn't just be "states" that would lose - it would be individual officers facing a twenty year stretch in federal prison for forcibly obstructing a federal agent.

Trump only stops if he is stopped, and that takes action.

Sure. It just doesn't take this action. If you're afraid of incipient lawlessness on the part of the government, it seems a little contradictory to advocate for state officials to start violating the law. I mean, not only is that ideologically inconsistent - but you're just creating the conditions under which emergency powers might properly be invoked. If state officials start using force against federal agents without any legal justification to do so, that's a lot closer to the circumstances where emergency powers can be deployed than just protestors blowing whistles on the street.
