How much can a state realistically hold off when Republicans control the house, the senate, and have a right leaning supreme court?

EDIT: In case it wasn’t clear this wasn’t sarcasm or anything. I’m genuinely curious.

I case you haven’t noticed, courts and law mean nothing to the incoming party. These states can come up with all of the lawsuits they want to, but it won’t do a bit of good.

What’s the worst consequence if I change my federal tax withholding and just not pay any more? Or send a USPS box full of dirty pennies instead?
