This sounds like the "can't squeeze blood from a stone" principle. If they don't have anything, you can't get it from them. But if they do have something and just won't give it to you, there are other ways to escalate.

Noncompliance with a court order is one of the worst situations to be in, because a court can order almost anything to coerce compliance, including getting your bank to just send the money to the plaintiff, freezing your bank accounts, sending a sheriff to take your assets, or putting you in jail for an unlimited time until you comply - this last one often happens when cryptocurrency is involved so the court can't actually seize it. They'll just jail you until you give it up. I think the longest contempt of court time was 20ish years.
