Nope. He needs more big balls and ask them: please show me the paper where you have a contract with me and I consent, where it says that you have any authority over my own money (BTC). I have no more fiat in bank, take them if you can.

You do not run away... you confront them and rebut their authority over you, the living man. That is the way people should do. Running away it means YOU AGREE with them but you violate their rules upon you. Rebutting their authority it means you make them OBSOLETE and you can live free wherever you want.
